I've now set up an UTF-8 message responder. Send an APRS message to 
the destination callsign UTF-8, and it will respond with 4 messages:

1. This message is English ASCII text.
2. This message is English UTF-8 text.
3. Finnish/Scandinavian UTF-8 chars: åäö ÅÄÖ
4. Japanese: 日本語 (3 chars)

The first two messages are sort of a joke, since both of those messages 
are both ASCII and UTF-8. There is no difference.

It's a bit simple, just threw it together quickly, so it doesn't do things 
like retrying message transmission. It does send message IDs and it does 
respond with an ack to incoming messages.
