xercesc transcoding to utf-8 on unix

[Brendan Miller]

If I'm not unix and I want to transcode to UTF-8, it sounds like I
need to use XMLPlatformUtils::fgTransServer->MakeNewTranscoderFor() to
make a transcoder. My question is, whether this will always work for
UTF-8. I'm on Linux, if I build without ICU, will transcoding to UTF-8
fail?

Thanks,
Brendan
