Wrong Codepage in w2a (src/Utility.cpp) because German letters are not translated correctly in error messages #133

I have an issue with error messages from ''RAISERROR'' because they are sent as UCS2 but on client side translated to ANSI (CP_ACP). If I change the first parameter of ::WideCharToMultiByte to CP_UTF8 (2 times) then all error messages are translated correctly.
You can test this with the sql statement

RAISERROR('größer', 16, 1)

complete source of w2a:

string w2a(const wchar_t* input)
    vector<char> messageBuffer;
    int length = ::WideCharToMultiByte(CP_UTF8, 0, input, -1, nullptr, 0, nullptr, nullptr);
    if (length > 0)
        // length includes null terminator
        ::WideCharToMultiByte(CP_UTF8, 0, input, -1,, messageBuffer.size(), nullptr, nullptr);
    return string(;

Thanks for this! I can fix it myself, but that will take a while. Or, you could complete a CLA and submit a pull request with this change. Unfortunately I wish I could say that it wouldn't take that long either, but it would probably be sooner than waiting for me to fix it.

Again, thanks for this.


I have compiled the sources on my machine and it works fine for me. I have already forked the source and commited the changes but it was a pain for me. I am new to git and it makes me crying! I love tortoisehg...
So I will look for this CLA and will send it to you.


I had also troubles at compiling the sources because it says that I have the wrong C++ version. I had to disable this warnigns in
c:\Program Files(x86)\MSBuild\Microsoft.Cpp\v4.0\V110\Microsoft.Cpp.Platform.targets
to compile successfully.
I have installed Visual Studio 2012 Professional but compiled with nodegyp. I read about changes in source code to make the things work a few months ago but for me it didn't work.
