Jason, thanks for the help.
1. Unfortunately, I'm getting an unhandled exception (access violation)
somewhere inside the call to transcodeTo(). Any idea why this would happen?
2. I'm also a bit fuzzy about the value of UTF8_MAXLEN. Would this normally
be 4 or so?
I'm using xerces 1.2, hope that's ok.
thanks!
