Just replying to myself - a simpler way might be to use the \x escape 
sequence in a string (I was reminded of this just now, it's in a comment 
about five threads down!) and then painting it using TextOut or something. 
But I'm fairly sure this only works in a Unicode / widechar string literal. 
(I can't find anything about it in the Borland help, only MSDN, so I'm 
guessing as to the behaviour using BC++.)

If you're using the VCL for output you still need to convert your Unicode 
strings to ANSI in the right codepage, as my first post discussed.  You 
could cheat and use a Unicode-aware VCL control too, there are some quite 
good third-party ones.

Finally I think assigning a WideString to an AnsiString performs some kind 
of conversion, but I don't know the details.  I'm pretty certain whatever it 
does is not overly reliable and doing it manually gives better results, but 
I honestly don't know.

Cheers,

David
