Not differently that with an "internal" font. Both kind of fonts are  
handled by fontspec the same way, they are of the same type, they're  
just loaded by different mechanisms (as you can drink beer from the  
bottle or out of a glass).

You can create a few (new) font families from the same font file(s)  
and give each a different set of features.

You can either make these special characters from another font active  
or set up character classes in which (many) different fonts take  
responsibility for a class (Unicode range of characters). Look into  
the archive, exactly one month ago, Wilfred Rooijen with CJK fonts!
