WorldScripts are indicated by ID number, i.e., certain resources falling
within a range of 512 different numbers = a certain script, depending on
what the range is. (As an aside, there aren't enough ranges defined, and
one is in effect limited to 512 fonts this way, but that's a minor gripe.
For Inuktitut I used Ethiopic script IDs.) For Simplified Chinese,
Traditional Chinese, and Japanese are all defined as different scripts. If
you wanted to have all three implemented you'd need (minimum) three
different fonts, as things are now.

It would also be nice if WG2 and UTC talked jointly about it aforehand.
There are some Apple supporters in WG2.

Such tagging is sort of what WorldScript does -- but it's defined by the ID
of the font being used to type at the moment. So somewhere (I guess within
Eudora) there would be a table relating the font ID to a language.
