Re: System fonts

[T . Slivnik]

Would it be helpful to have a concept of a "font package", i.e. an 
abstract font which contains no glyphs but rather itself contains only 
mappings to glyphs of other fonts.

The mapping could work on an individual glyph basis, or on the basis of 
character code ranges, e.g. a font package Times+CJK.fpack could be a 
file like this:

0x0000-0x00ff  Times.font
0x0100-0xffff  CJK.font

This would allow you to combine several proprietary fonts into one of 
your own without violating any of their IP.

E.g. if you have a font with a nice Roman range but no CJK, and another 
font with an ugly Roman font range but which contains CJK, you could 
combine them into a single "font package" and use that as your default 
system font?

This could result in a "font substitution" effect which is efficient 
and also under clean and transparent control of the user.
