As I understand it there are two modes, one that is 16x8 and the other
16x9 but each character or a group of characters can be switched into
the mode at a time. i.e. 16x9 and 16x8 can be mixed, as in the standard
ROM font. 

In the 16x9 the nineth bit is always the same as the eighth, so that is
half your problem.

The other half is more trickey, I have the Tech manual at home, but it
is not very enjoyable reading, i.e. you have to flip back and forth and
piece together the information from half the manual to something 10
pages away and it is not even well cross-referenced.  I solved that
problem by using the graphic characters of the ROM fonts when I needed
16x9 characters.  That is the easy way, if you don't need the standard
graphics characters.  If that does not give you enough flexability, I
hope someone else answers your questions.

If you get a better solution please send it to me.  If you don't, write
back and I'll try and read the manual one evening.

I hope that helps,
