OpenType allows for substitution of language-specific glyphs and many
script and language tags are already "registered".
However, the last time I checked (quite recently), the Uniscribe engine
only implements one language tag per script.
OpenType is still nascent and tremendous strides have been made within
the past few years. Once implementations do allow for multiple language
based substitutions under a single script tag, there should be much
improvement in browser display. (As long as the fonts get updated, too!)
Meanwhile, the workable approach seems to remain assigning specific
fonts in the style declaration.
