It looks as though the ucs2() has been depracated in favor of utf16 in Qt4.
What I've been trying to figure out is what it means that Xerces C++ and
Linux wchar_t don't get along well. I wrote the functions below in order to
find which, if any, characters are not identical. I left out a few which I
do not understand, and didn't want to research. I left the chNEL in even
though I don't know what it's for. It is not part of ASCII, and therefore
not part of the C++ basic character set. All the other XMLCh characters match
their wchar_t counterparts on my SuSE Linux 10 system.
