Specifically:
Unfortunately, I'm still a bit confused how people handled other data on LiveJournal-- should fullnames on friends lists be transcoded? Does LiveJournal just pass the eight-bit data directly, then, without urlencoding? (I assume so.) But this is at least a step in the right direction, and with the feedback of someone who actually needs this functionality I think I can make it work.
Doubly unfortunately, this code is really obsolete-- anyone using LiveJournal now is probably using UTF-8 which makes all of this issue moot. But there are still other non-LiveJournal.com LiveJournal sites, and I'd like to finalize this issue before releasing LogJam 3.0.5 which fixes a few minor bugs.
