ANSI to UTF8 (dynamic mem alloc?)

[Souldrift]

Good morning :), got a question to the following code piece which converts ansi text to UTF8.

void SynthesizerSvox::ANSI2UTF8( char* text, int size, char*& result )
{
const int SIZE = 10240;

if( result ) 
{
	delete \[\] result;
}
result = new char\[SIZE\];

WCHAR w\[SIZE\]={0};
int erg=0;

erg=MultiByteToWideChar(CP\_ACP, 0, text, -1, w, SIZE / sizeof(WCHAR));	// ANSI to UNICODE
erg=WideCharToMultiByte(CP\_UTF8, 0, w, -1, result, SIZE, 0, 0);		// UNICODE to UTF-8

}

I found the code somewhere on the net (thanks!) and it works nicely. Only I´d like to work with dynamic memory allocation (don´t like to limit it) and can´t seem to get it done. The number of bytes used per character vary in UTF8 character set. Is there a solution to this? Souldrift

Why?

Yes, but WideCharToMultiByte is able to tell you how many bytes are required (MSDN [^]):

cbMultiByte [in] Size, in bytes, of the buffer indicated by lpMultiByteStr. If this parameter is set to 0, the function returns the required buffer size for lpMultiByteStr and makes no use of the output parameter itself.

Hm, good point. Thanks for reminding me of my ability to read ... it worked ;). Cheers Souldrift
