Dear List,
What would be the best of transcoding to an encoding. The following
seems to be the prevailing approach
XMLTransService::Codes reasonForFailure;
unsigned TRANSCODER_MEMORY_BLOCK_SIZE = 16 * 1024;
XMLTranscoder* m_utf8Transcoder =
XMLPlatformUtils::fgTransService->makeNewTranscoderFor( "ISO-8859-1" ,
reasonForFailure , TRANSCODER_MEMORY_BLOCK_SIZE );
XMLSize_t charsEaten;
size_t len = XMLString::stringLen( chars );
XMLByte* byte = new XMLByte[ (len*4) + 1 ];
unsigned outLen = m_utf8Transcoder->transcodeTo( chars , len , byte ,
len*4 , charsEaten , XMLTranscoder::UnRep_Throw );
byte[outLen] = '\0';
Three questions arise:
1. Why is XMLByte* byte allocated almost 4 times the memory it should need?
2. Can XMLTranscoder* m_utf8Transcoder be created once and called
repeatedly?
3. Is the above methof of trabscoding preferred to the simpler technique
TranscodeToStr transcoder( chars , "ISO-8859-1" );
const XMLByte* str = transcoder.str();
Thanks,
