You say you're getting this value originally from an Apple event, but you
don't say what Apple event it is. It might be crucial to know that. I ran
into a situation recently where I was getting back a UTF-16 bytestring and
the receiving program (parallel to your Pascal situation?) didn't know what
to do with that. Like your example, it *looked* right, but that was because
I couldn't see the null characters between the visible characters. m.
