Based on discussion here and at the W3C TPAC last week, I raised this 
issue on the apps-discuss list:

http://www.ietf.org/mail-archive/web/apps-discuss/current/msg03447.html

The immediate reaction was: "do you mean fonts or typefaces?"

Before taking on this work, it would be helpful to understand exactly 
what typographic entities are being sent around by browsers and other 
applications.
