In order to do this, we need to go through I18n for this. SIP use MIME formats and can specify character set used.  Default is UTF8, like in IAX2. I don't know what Skype uses, but if I remember correctly, XMPP is not pure UTF8, but a special XHTML profile - so we're suddenly adding formatting.

In XMPP and SIP we also have two different concept - a message, like an SMS text and a chat session. A chat session in SIP is in some clients handled by the MSRP protocol. 

In Asterisk we also have realtime text, T.140, which needs to be gatewayed to chat-like sessions and instant messages. And don't forget the SMS app...

We should propably investigate IRC and Twitter protocols as wells.

So we have
 - character by character (T.140), one-shot messages (SMS, SIP Message, XMPP) and chat sessions (SIP/MSRP, XMPP)
- formatted and non-formatted messages (raw text and various markup languages)
- character sets

Just some input after a few years of thinking...
