Comment 7 for bug 321246

Actually, the nick in nmdc should be treated as a binary blob and kept separate from the display nick (which probably should be converted disregarding encoding errors...)...then findlegacy would not have to bother with encodings at all...
converting everything to utf8 in nmdc is not very friendly towards other clients / legacy users.
we've covered this before in other contexts I believe, but noone's cared enough to actually fix it...
