That's really interesting.  I had interpreted the EMF documentation
differently; wherever it refers to "unicode", I had understood that
to mean "any multibyte encoding" and thus concluded that the wide
character versions of all the text routines were necessary.  
But hey, if it works - that's great.

Seems only fair.  Until recently the EMF output was interpreted
fine under linux but crashed the Windows viewer :-)
Could you send me a sample EMF file that OpenOffice has troubles
with?  I have a couple of other EMF viewers that I run under linux
and I'm curious what they think about it.

Do you know if the various other terminal types do anything
reasonable with CP950 fonts?  That is, should we add this to the
list of supported encodings in the "set encoding" command?
