Thank you! It didn't seem to break anything, unlike using UCS-16 which 
contains null bytes, which some broken software cut strings at.

By coincidence, on Monday I added UTF-8 support on aprs.fi. The UTF-8 
responder is running again, too (now under supervisor so that it will get 
automatically started on boot).
