Hi, i've noticed the leak when running the following code:
while(true)
{
XMLTranscoder* utf8Transcoder;
XMLTransService::Codes failReason;
utf8Transcoder =
XMLPlatformUtils::fgTranscService->makeNewTranscoderFor("UTF-8", failReason,
16*1024);
size_t len = XMLString::stringLen(value);
XMLByte* utf8 = new XMLByte[(len*4)+1];
unsigned int eaten;
unsigned int utf8Len = utf8Transcoder->transcodeTo(my_hebrew_string, len,
utf8, len*4, eaten, XMLTranscoder::UnRep_Throw);
utf8[utf8Len] = '\0';
string str = (char*)utf8;
delete[] utf8;
}
Also, how can i accomplish the opposite task of convert an std::string to
XMLCh* without using the regular "transcode" function?
my string contains non-english characters and i need to convert it to an
XMLCh* ... how can i do that?
Thanks again
