OpenType has a GPOS table which deals with this kind of thing. I'm not
sure if Type1 has an analogue (well, I guess it does : the GPOS table in
Type1-style OpenType fonts. ;)

But BDF fonts have nothing along these lines. This is something that will
have to be defined. I envisage extra data in BDF and PCF fonts, and
possibly some magic extensions to the renderer that activate if the XLFD
ends with -iso10646-1. (Kerning is a similar issue, might look at how that
is done or not done).
