Not easily.  Traditional Chinese, simplified Chinese, Japanese and Korean
fonts cover the same Unicode regions, and fonts for all of these languages
generally cover only a fraction of the total space making any coverage 
based language tag only a guess at best.  In particular, we'd need to call 
upon an expert in the area of the two Chinese varients to get an idea if 
there were any codepoints distinguishing the two.

This is a minor issue by comparison, but the same basic problem.  We'll 
see if people using that language start to rise up in revolt as the Han 
language groups have, then we can start looking for yet another kludge.
