Hi,
you need to allocate at least one extra character (i.e. stringLength+1)
to store the NULL character.

the signature is

*const /charSizes)/

//It takes XMLByte* (i.e. unsigned char*, that you should get from
std::string.c_str() ) and fills an XMLCh buffer of maxChars.

Hi, first of all, thanks for your reply
I tried to use the "transcodeFrom" function using the following code:
XMLByte* xmlBytes = (unsigned char*)MY_STRING.c_str();
size_t stringLength = str.length();
XMLCh* xmlChars = new XMLCh[stringLength];
XMLTranscoder* utf8Transcoder ;
XMLTransService::Codes failReason;
utf8Transcoder =
XMLPlatformUtils::fgTransService->makeNewTranscoderFor("UTF-8", failReason,
16*1024);
unsigned int eaten;
unsigned char* charSizes = new unsigned char[stringLength];
unsigned int xmlCharsLength = utf8Transcoder->transcodeFrom(xmlBytes,
stringLength, xmlChars, stringLength, eaten, charSize);
delete[] charSizes;
delete utf8Transcoder;
...
XMLString::release(xmlChars);
The problem with this code is that for each string that i transcode i get
some weird chars from the right side. For example, if i transcode the string
"Hello", then my XMLCh* will be "Hello$$$$".
I tried the place a null ('\0') at the end of the XMLCh but it causes an
exception to be thrown when i try to call XMLString::release, to deallocate
it's memory.
How can i solve this?
again, thanks for your help :)
