Very long names filled with garbage characters break the Blizzard UI. Specifically, it takes a very long time to render them and lags the entire UI, including the game, while it is trying to do so. Combined with the current issue of false names, this can lock my game up for minutes at a time. I suggest two measures to counteract this:

1. Remove all names that contain the '?' character (Wow's substitution for non-ASCII character sets) as they are not ever legal.
2. Truncate all names to 12 characters before displaying (both in the HonorSpy pane and when reporting on pruned players)
   2a. It would be useful to have some configurability on the removal of pruned players in general, as it is quite spammy.

I appreciate addons take work so I'm happy to PR this stuff.
