Chinese characters cause «String conversion error: Illegal byte sequence encounted in the input.» #7117

Hi I’m running a dot net application under windows with mono. I have created library in C program to load my dot net application, but i found a bug in g_utf8_to_utf16 function.When my program is placed in a path with a Chinese character,mono can not load assembly, and all Chinese characters in path become messy codes. It causes the program can’t work correctly. After referenced the source code, I found that this is the result of the error of the g_utf8_to_utf16 function, it converts English characters but does not convert Chinese characters, eg ‘汉’. it will throw «String conversion error: Illegal byte sequence encounted in the input».This made me quite upset,because my program will run on the Chinese version of the Windows,I really do not know how to do. I think mono should support Wide char(wchar_t),That will make it easier for people in more countries to use.

The text was updated successfully, but these errors were encountered:

Could you help us to reproduce the issue with the sample we can use?

This is my C program:

After debugging,I found where the problem was : mono_file_map_open

Is there any other solution to this problem?
Or are some of the parameters not set right?

@jaykrell are you familiar with this code?

Call stack would be nice.

Windows 8 bit strings are generally not utf8, but are being treated here as so.
That is likely the problem.

The right fix is that mono should use unichar2 or wchar_t (more) extensively and avoid converting to 8 bits, except at the Posix boundary. This is how Windows works and is not unreasonable for all software. wchar_t is widely supported, not just on Windows. It doubles or quadruples some memory use, but that is already largely happening anyway. We and much other software already traffic extensively in wchar or unichar2 on all platforms.

1 The obnoxious non-fix is to tell user to call MultiByteToWideChar(CP_ACP) and then WideCharToMultiByte(CP_UTF8) on all 8 bit input before passing it to mono.
He has done something likely invalid but only subtley so.

2 A practical and friendly fix is wherever monoapi has mono_foo(const char* presumed_utf8) also
provide mono_foo_w(const wchar_t*), implemented by converting to utf8 and calling mono_foo.
(Very long term, the layering could/should be reversed, but that is probably never.)

«w» is for «wide» — for any given string-taking function CreateFile, Windows actually has CreateFIleW that takes wchar_t and CreateFileA that takes an 8bit string, in code page that can vary per user and per thread but is rarely UTF8 (only recently did Windows allow UTF8 as the implicit codepage).
While this ugly to be sure, it is a widely used existing practise and does work.
So follow that on a small scale. To start, one function, mono_domain_assembly_open_w.

The user’s code would remain invalid and not working, but easy to fix.
He would change char to wchar_t and A to W, «str» to «wcs», and append «_w» at the mono boundary.

3 Another gross fix, and risky because it might not work, is to try to pass the string through unmodified, to fopen instead _wfopen. This is risky because it depends on carefully never assuming the encoding of user input, and assuming whatever we pass it to agrees (it would in this case). And we’d have to discern user input from our own utf8 data. If our data is always 7-bit clean, then it is viable.

I suggest 2. It is small. It can be done incrementally but will never be huge — a bunch of one liners. It doesn’t contradict 1 or 3, but is more practical than 1 and more helpful than 3.

Exception in AST.Declaration VisitClassTemplate #1165

Brief Description

I am trying to create a cs interface to my c++ project under linux. I am using CPPSharp.CLI.exe and am running the latest master build and latest clang + llvm. I also tried the last stable version 0.8.22 with exact matching llvm and clang refspecs and experienced the same issue:

Not able to convert the type CppSharp.Parser.AST.ClassTemplateSpecialization (CppSharp.Parser.AST.DeclarationContext::basic_istream) since the resulting type CppSharp.AST.Class (std::basic_istream) cannot be cast to AST.ClassTemplateSecialization.

At a later stage I now get an Exception, but that may be a different issue.

Weird `ExecutionEngineException: String conversion error: Illegal byte sequence encounted in the input` on Windows about kspe HOT 1 OPEN

There’s very good chance that we may be dealing with an environmental problem (or, at least, trigger).

In order to use it, one need to unzip it somewhere and then:

/Workspaces/…. should be replaced by the pathname of your KSP’s rigs you wanna test (yeah, you can run it on more than one). If the pathname have spaces or similar weirdyties you need to use double quotes on the pathnames:

The output will be something similar to this:

Assemblies that eventually fail the check will have an Exception name instead of an Ok on the line.

You can (or should) redirect the output to a file, so you can attach it on a post here or send me by mail:

A file called results.txt will be created on the current directory with the output.

WinForms applications crash when a specific text is pasted into any control that can accept text. #18923

I just wanted to paste a piece text from Wikipedia in a Winforms application.

A similar bug reported in the xamarin bug tracker but no progress with it since 2017: https://xamarin.github.io/bugzilla-archives/60/60819/bug.html

Steps to Reproduce

  1. Paste following text into any RichTextControl, Textbox or anything that accepts pasted text: «Benzo[a]pyrene is a polycyclic aromatic hydrocarbon and the result of incomplete combustion of organic matter at temperatures between 300 °C (572 °F) and 600 °C (1,112 °F). The ubiquitous compound can be found in coal tar, tobacco smoke and many foods, especially grilled meats. » in a Winforms application. It even crashes if you paste into a file open dialog.

Apparently the issue is with the ° mark.

Current Behavior

Expected Behavior

It doesn’t crash and is able to handle the conversion (even if that means including a � instead.)

Memory layout of structures returned by Sharedspice callback function SendData()


Created:

2021-12-20

Updated:

2021-12-29

  • gel-division

    I’m attempting to build an interface for ngspice.dll through a C# caller app. I’m currently attempting to read the data ngspice.dll sends back during a transient analysis through the callback function SendData().

    The pointer to the vecvaluesall struct that is sent by sharedspice is read correctly by the C# caller (correctly parsing veccount, vecindex and vecsa). However, I’m having some trouble with the vecvalues struct array that is returned in pointer form though the vecsa variable

    Firstly, I cannot get the char* name variable of vecvalues to parse correctly. I’m currently storing the char* object as a C# IntPtr, just storing the pointer in integer format. However, as soon as I attempt to access the text data at this unmanaged memory location through Marshal.PtrToStringAnsi() (ANSI format) or Marshal.PtrToStringUni()(Unicode format), I get errors such as ExecutionEngineException: String conversion error: Illegal byte sequence encounted in the input., or the returned string from the Marshalling function is a couple random characters.

    Furthermore, I’m uncertain whether I’m reading the values of creal, cimag, is_scale and is_complex of the vecvalues struct correctly, as creal and cimag seem to yield extremely high positive and negative values.

    I’d appreciate some help on the memory layout of the vecvalues structures that are returned. I’ve tried defining my structures in C# with normal, explicit (tried padding with both 4 and 8 bytes) and sequential layouts, however, none of these options seem to yield correct results.

    Is ngspice.dll compiled in such way that each variable of the structure vecvalues are memory aligned? Or are the variables packed (perhaps in the interest of saving memory space)? Where might I be going wrong with the parsing of char* name from unmanaged memory?

    Below is my structure definitions in C# (variables names are slightly different to ngspice manual):

    public struct vecValuesAll          //this definition works as intended
    {
        public int vecCount;
        public int vecIndex;
        public IntPtr vecArray;
    };

    [StructLayout(LayoutKind.Sequential)] public struct vecValue      //this doesn't seem to work correctly
    {
        public IntPtr vecNamePtr;
        public double cReal;
        public double cImag;
        public bool isScale;
        public bool isComplex;
    };

    [StructLayout(LayoutKind.Explicit)] public struct vecValue       //assigning explicit memory offsets like this (word size of 8) also doesn't seem to work correctly
    {
        [FieldOffset(0)] public IntPtr vecNamePtr;
        [FieldOffset(8)] public double cReal;
        [FieldOffset(16)] public double cImag;
        [FieldOffset(24)] public bool isScale;
        [FieldOffset(32)] public bool isComplex;
    };

    Any help is appreciated. Thank you.

    ngspice uses c null-terminated, utf8 encoded standard strings. There is no memory management beyond allocating (and de-allocating) the memory on the heap.

    How do you get from vecArray to vecValue ?

    Is IntPtr the right thing? There is some discussion in the web on integers in 64-systems may truncate a pointer. See https://forum.unity.com/threads/problem-marshaling-c-char-to-string.731822/

    The structs directly access the internal storage areas of ngspice. There is no special copying of data. So you have to take care that the data vectors in their plots are still available (no commands ‘destroy’ or ‘unlet’ given before evaluating the vectors pointed to, for example).

  • gel-division

    Thanks very much for your suggestions. Unfortunately, I’ve not been able to fix the issue. Let me answer your questions and describe what I’ve tried since.

    How do you get from vecArray to vecValue ?

    I’m getting the vecsa pointer of the vecvaluesall structure that is sent by callback SendData(), then incrementing through memory locations directly, using the code below.

    var size = Marshal.SizeOf(typeof(vecValue));                        //get unmanaged size, in bytes, of the structure type 'vecValue'
vecValue[] mangagedArray = new vecValue[length];                    //define 'mangagedArray'

for (int i = 0; i < length; i++)                                    //increment through vector array (length = vecValuesAll.vecCount)
{
    IntPtr nextStructureMemBlock = IntPtr.Add(unmanagedArray, i * size);        //increments pointer memory location to position of next struct in array (by incrementing through memory by the size (in bytes) of 'vecValue' structure)
    mangagedArray[i] = Marshal.PtrToStructure<vecValue>(nextStructureMemBlock);        //converts the memory block to a structure and copies it to the managed array
}

    I’m not 100% confident that this method is correct, so for my testing of the main string conversion issue, I’ve mainly tried accessing mangagedArray[0], which should hold the first vecValue object, directly following the pointer location sent by vecValuesAll.vecsa.

    Is IntPtr the right thing? There is some discussion in the web on integers in 64-systems may truncate a pointer. See https://forum.unity.com/threads/problem-marshaling-c-char-to-string.731822/

    I may be mistaken, but that thread seems to mention this truncation issue occurring on the C application side, and not the C# caller’s side? Some googling seems to show that IntPtr is either 32 or 64 bit depending on the system that is being run? So… I’m assuming this particular problem shouldn’t be the issue…?

    The structs directly access the internal storage areas of ngspice. There is no special copying of data. So you have to take care that the data vectors in their plots are still available (no commands ‘destroy’ or ‘unlet’ given before evaluating the vectors pointed to, for example).

    I assume this isn’t an issue if you directly run the conversion functions directly from inside the SendData() callback function (which is what I’m currently doing, at least for the purposes of testing)?

    Also, thanks for clarifying which type of string ngspice returns. I don’t think the two methods that I used, Marshal.PtrToStringAnsi() and Marshal.PtrToStringUni() supports UTF-8. So, I attempted the method below to convert the string:

    unsafe{
    int length = 0;

    for (byte* j = (byte*)vecValue.vecNamePtr; *j != 0; j++, length++);        //starting from the pointer location, increments through memory until null terminator is found, to determine length of string

    var clrString = Encoding.UTF8.GetString((byte*)vecValue.vecNamePtr, length);       //gets string using pointer
}

    This method does not work, unfortunately, as it just produces a string with mostly gibberish (see my example below).

    A few other things of note: Each execution of my Unity app, when the netlist is entered, and transient analysis is run, the values of vecValue[0] changes between each execution. No difference in netlist, etc, but the parsed data of vecValue[0] differs between executions. I’m assuming this means I’m reading incorrect areas of unmanaged memory, which most likely means the marshalling of the structure vecValue from unmanaged memory is not happening correctly.

    And, here is an example of the parsed data of vecValue[0] from one such instance:

    name = @�R~�
creal = 9.66914275052348E-312
cimag = 9.66914275004918E-312
is_scale = True
is_complex = True

    As can be seen, the string conversion is clearly wrong, and I think the numbers are as well, since they seem way too small.

    Thanks Holger Vogt for your help so far, really appreciate it.

    What about this:
    https://www.codeproject.com/Articles/32125/Unmanaged-Arrays-in-C-No-Problem

    Thanks for the link. I had a look, and I’m having trouble understanding whether it is really necessary to define and deal with unmanaged arrays inside my C# caller. Should I not instead attempt to parse the unmanaged memory into a managed array, so that I can access that data in a safer way? The tutorial at the link also lists one of the reasons for defining unmanaged arrays as being if bidirectional communication with unmanaged code is necessary. I don’t require this, I only need to read the data. Please do let me know if my line of thinking is incorrect.

    I decided to address the issue of the incorrect parsing of unmanaged memory by taking a look at the raw bytes of memory. I’ve done this with the following snippet, which is run every time SendData() is called by Ngspice.

    var arr = new byte[128];            //stores raw bytes from memory
string rawByteString = "";          //stores bytes as string

Marshal.Copy(vecValuesAll.vecArray, arr, 0, 128);      //copy bytes from memory (starting from location of pointer vecValuesAll.vecArray) into byte array

for(int i = 0; i < 128; i++){                       //copy byte array to string to view in readable format
    rawByteString += arr[i].ToString();
    rawByteString += ", ";
}

Debug.Log(rawByteString);       //print to log

    I ran my C# caller repeatedly, each time, it sent the following commands to Ngspice:
    remcirc
    circbyline RC Circuit
    circbyline V1 n1 0 5V
    circbyline R1 n1 n2 1k
    circbyline C1 n2 0 100F ic=0
    circbyline .end
    tran 1ms 10ms

    Here are the results:

    Image

    Direct link: https://i.imgur.com/AScGRb5.png

    Leftmost column is the data at the pointer vecValuesAll.vecArray, with data moving towards the right showing the data in memory past the location of the pointer. Each row of data is a different execution of my C# caller. I’ve broken the bytes up into blocks of 8, the word size as I’m on a 64-bit system.

    I’ve colour coded what I understand should be the first three structures of the struct array. (5 blocks of 8 bytes, each block of 8 corresponding to one variable of the vecValue structure, allowing for structure padding)

    Correct me if I’m wrong, but the data looks flat out wrong. There is massive amounts of variability between each successive run of the application, when, theoretically, the only data that should be different is the char* name. I also can’t find the corresponding memory areas which represent the Boolean values of the structure, which should (as I understand it), simply be a single 1 or 0 on the leftmost column of a block of 8 bytes, allowing for padding.

    I’m starting to think it may be a lot simpler to write a small translation CLI program in C/C++ which provides an interfaces between Ngspice.dll and C#, converting all this vector data into simple stdout.

    I do not know C#, but my guess is that the code lacks a pointer dereference step. Structure member vecsa is a pointer to an array of pointers to structures, as can be seen in this line from the example code:

    v2dat = vdata->vecsa[vecgetnumber]->creal;

    Three dereference steps are need to go from function argument to data value.

    Also, it seems very unlikely that the C compiler would allocate 8 bytes for a bool. ngspice’s own bool.h has:

    typedef int bool;

    • gel-division

      Structure member vecsa is a pointer to an array of pointers to structures

      Holy cow. I cannot thank you enough for this.

      All the hours I spent banging my head against the table… I was working under the assumption that vecsa is a pointer directly to the array of structures, not a pointer to an array of pointers, with each pointer in the array addressing a structure.

      I have finally got it working!

      Also, it seems very unlikely that the C compiler would allocate 8 bytes for a bool. ngspice’s own bool.h has:
      typedef int bool;

      I unfortunately think I lack the knowledge to find a good testing methodology for whether the booleans of the vecvalues structure are being parsed correctly. I don’t think I need these variables for my use case, so I’m not going to worry too much about these for the time being.

      For anyone stumbling across this thread in the future, as @h_vogt stated here that Ngspice currently doesn’t have any example code for interfacing sharedspice with C#, so I’ve put together a sample script of my work here, on GitHub. I’ll update the sample script to include this functionality for reading the structures returned by SendData().

      Once again, @gatk555, my sincerest thanks. I had actually given up on my direct C# interface and began putting together a C++ console app to handle communication with sharedspice, before I saw your response 😅

    You are very welcome. I think congratulations are due for getting such a disparate set of software components to work together.

    Would it be rude to ask what you are building? My favourite guess is a game whose player must solve a series of electronic design and repair puzzles.
