Ahh.. that's interesting. I suspect something is delivering
unicode-based server-IDs inside the IntroducerClient, when it's supposed
to be using plain strings. It's a bug inside tahoe, not user error. I
bet it has to do with the introducer_cache.yaml file.

I've opened https://tahoe-lafs.org/trac/tahoe-lafs/ticket/2817 to track
this one. I'll see if I can figure out what's going on later tonight.
