Hello, I've found that the upperCase() method in the native transcoder is completely screwed up in version 1.1.0.d05 on linux. Here's a working version (in file $(XERCESCROOT)/util/Transcoders/Iconv/IconvTransService.cpp)
void IconvTransService::upperCase(XMLCh* const toUpperCase) const { XMLCh *p = toUpperCase; for ( ; *p != 0; p++ ) { *p = towupper(*p); } } J. Cameijo Cerdeira
