Looking att protocol examples from jabber.org:

<message language="swahili" encoding="ISO-whatever-1234">
  <to>mbwana</to>
  <say>barbarbar!</say>
</message>

... or something the like. This raises the interesting question about
the <to></to> field. Should it also be able to contain non-us-ascii
characters? That could cause some complications for clients, right? If
a Japanese person's name contains Kanji or Furigana characters, his
name would be something like* "ÃUåS". We probably want to enforce user
IDs in us ascii, though at least some roster info can be in any
encoding... except group names and such.

* typical; my netscape on Linux actually displays Kanji correctly.
  Let's cat /bin/uname instead.
