It was my understanding that except for possibly some header information & endianess, UTF-32 is the same as UCS-4 valuewise. The difference is that UTF-32 is an encoding, UCS-4 is a character representation scheme. Is this correct? If so, I don't think it's absolutely correct to say what range UTF-32 can represent. There's so many Uxx acronyms around that it's very confusing for a beginner. Correct me if I'm wrong - UCS-2, UCS-4, & Unicode are for talking about character representations. UTF-x mean encodings. BTW, thanks to all that have contributed comments to this thread. I'm finding the feedback very helpful. -allan
