You don't say how the macro X() is implemented; also, beware that you
are putting in "len" the ASCII length of the string, and that could be
different from the the UTF-16 length.
The correct code would involve two transcoders, one from the encoding
you know is used for the "buffer" variable to Unicode, and one from
Unicode to UTF-8.

I am using xerces 2.8 in C++ API
I created a function to convert to UTF8
void convertToUTF8(const char* buffer, string &utf8_string)

XMLTranscoder* utf8Transcoder;
XMLTransService::Codes failReason;
utf8Transcoder =
XMLPlatformUtils::fgTransService->makeNewTranscoderFor("UTF-8", failReason,
16*1024);
size_t len = XMLString::stringLen(buffer);
XMLByte* utf8 = new XMLByte[(len*MB_LEN_MAX)+1];
unsigned int eaten;
unsigned int utf8Len = utf8Transcoder->transcodeTo(X(buffer), len,
utf8, len*MB_LEN_MAX, eaten, XMLTranscoder::UnRep_Throw);
utf8[utf8Len] = '\0';
utf8_string = (char*)utf8;
delete[] utf8;
delete utf8Transcoder;
}
But this function leaks memory when I pass it through the Purify tool to
detect memory leaks.
[I] MPK: Potential memory leak of 4164 bytes from 214 blocks allocated in

Is there something I need to do explicity to release the memory?
Please let me know.
Thanks
