Duhh! How did I manage to miss that? I did convert the numbers to hex
(or I thought I did ... maybe I was trying to convert them *from* hex
to decimal).

Got it, thanks.

Actually, I'm a step ahead of you on that one. I already made sure to
compile it with -DSP_MULTIBYTE (actually, I think that's the default
when you compile it from the Jade distribution ... anyway, I made sure 
of it).

According to the original SGML standard, no. But there are Extended
Naming Rules which supposedly do allow you to use any character set,
provided that you specify it properly in the SGML declaration. Or so I 
gather from several very cursory sources. My searches of the Web and
Deja News give me the strong impression that very few people, even
among SGML wizards, really understand how it works.

Ha-ha. I really should one of these days, shouldn't I. Unfortunately
SGML is another one of those standards you have to buy from ISO
... it's 200 bucks or so. So, one of these days ...

Thanks once again, guys!
