Unicode

I need output file in UTF-8. There is an NSIS plugin which converts between ASCII and various Unicodes, but not between UTF-16 and UTF-8.

Since I had to cope with the Unicode.dll last week, I added the missing routine FileUnicode2UTF8 to Unicode.dll.


int WideCharToMultiByte(
__in UINT CodePage,
__in DWORD dwFlags,
__in LPCWSTR lpWideCharStr,
__in int cchWideChar,
__out LPSTR lpMultiByteStr,
__in int cbMultiByte,
__in LPCSTR lpDefaultChar,
__out LPBOOL lpUsedDefaultChar
);

According to Microsoft's documentation WideChar2MultiByte should return the BufferSize needed if parameter cbMultiByte is 0, i always got 0.

So to convert a file to UTF-8 I make the buffer as large as the inputfile (Unicode-16) and if the function returns "ERROR_INSUFFICIENT_BUFFER" I reallocate the buffer with double the size and repeat.

I hope It will be of use.
