Kelly, IIRC, OS9 will support a full 256 char font set. Some are only accessable by certain codes, but I'm pretty sure the support is there. 256 would most likely be the limit though.

Thanks Robert.  I didn't realize
that NitrOS9 built its own font set from a 
source file.

I can see now why I
can only access 128 characters with the rest appearing 
to be blank.

It is all
that is defined in the 8x8 set and then it changes to a different 
set of 6x8
characters mapped to buffer 2.

Is 128 characters the limit per buffer?
