[XeTeX] using font pairs (probably a fontspec question...)

[Michiel Kamermans]

Hi all,

a question about using multiple fonts. I have several fonts that cover 
the vastness of unicode *as a set* -- Han Nom A + Han Nom B, Code 2000 + 
2001 + 2002, etc. -- which essentially need to be used in conjunction 
with each other when writing documents that use characters from 
different (vast) unicode blocks while visually using the same "font". Is 
there a way to tell fontspec to consider certain collections of fonts 
fixed sets, when you know certain fonts were specifically designed as 
one font, split up over several separate files?

I'd also like to stress the "knowing" bit: I know that Han Nom A and B 
form a one font, in two files. Similarly, I know that Code2000, 2001 and 
2002 form one font, in three files. I'm not looking for general font 
linking (there are pros and cons to general font linking; it's okay if 
you can predict what will happen, and it's stupid when you don't know 
the fonts you're using so you can't predict which font will catch which 
glyph). In this case, I know the fonts cannot clash, because they were 
specifically designed that way, so I need some way to tell fontspec "do 
not look in just ..., but if it's not in there, look in ... because 
that's where it's *supposed* to be by design".

Is this possible?
