Why is it wrong of us to expect font combination/substitution to work
when the functions are offered by the underlying system we're using?
Other systems appear to have that working, but they're no GNUstep.

Why is this not true for aliases? At any point in time, a given alias
resolves to a particular set of glyphs.

I think we don't really understand why there is a problem yet and
many of the people who do need this functionality have English as a
second language and not always a particularly strong one.

It's all well and good saying "write this missing code" but as far as I
can tell, the code about this in back-xlib isn't very commented, so it
feels like coding in the dark with one hand tied. :-( Can't even tell
what the code needs to do yet, let alone try to write it.
