locales and fonts

[Albert Cahalan]

What characters are required? Without such a list, font requirements
are a complete mystery. I'd particularly like to know the 1024 most
important Latin-style (including Greek and Cyrillic) characters so
that I can make a better console font. For example, there is a picture
of the Rwandan characters on the wiki but no code points. Finding the
characters in a great big font full of similar characters isn't easy.

What locales will be supported? For example, Tux Paint uses rw_RW.UTF-8
for Kinyarwanda, with the locale data stored as "rw" since there is no
other rw_* locale. Would the XO localization recognize "rw" alone?
(as it should AFAIK, with graceful fallback from country-specific to
language-only)
