I managed to get UTF-8 communications with Lispworks working (on Linux). Unfortunately I had to use flexi-streams to do it, so it's probably not suitable for inclusion in Slime proper. It doesn't look like Lispworks's SOCKET-STREAMs are capable of external-format translation, which is too bad.

At least now I can work on internationalized stuff without having my Slime session just die every time a non-ascii character tries to get printed! Hopefully this can help someone else as well.
