[SM-USERS] How to force UTF-8 charset for all languages

[<squ...@lm...>]

Hello all,

I there a way in squirrelmail to force the UTF-8 charset
for all interface languages (or for e.g. only de_DE).

I need to use UTF-8 for the user-interface (HTML output/input)
and for the e-mails encoding (no latin1 anymore).

There are major problems for users with e.g. a german interface
which want to send e-mail in russian or greek.

Regards valli

PS: Why is UTF-8 not the default charset for all languages?
    Is the '$default_charset' setting only usefull together with en_US?
