Firefox has separate font preferences for script/langGroup and it does honor
lang/xml:lang when selecting fonts. If lang/xml:lang is not specified, it falls
back to script/langGroup inferred from charset (that does not always work, but
in many cases, it works more or less).  Of course, documents encoded in
UTF-{8,16,32} (or with a lot of NCRs to represent characters outside the
repertoire of the current charset), this breaks down. For UTF-{8,16,32}, it
falls back to the font for the lang/scriptGroup corresponding to the current
application locale. (its lang/scriptGroup is not optimal being written almost
10 years ago. It'd be done differently if it was to be done today). 

I have a partial patch in that direction, but it's not anywhere near to be
complete.

WebKit currently has only a single set of font preference across all
languages/scripts.  |Settings| in webkit is not expressive enough (because it
does not have a general 'key-value' with or without hierarchy) to have these
font preferences.

font.<script>.serif
font.<script>.sans-serif
font.<script>.monospace

As for Han-disambiguation and Cyrillic-lang dependency, we need to do more than
the above, but the above is a start.
