Can't be fixed until we move the msay panel to goonchat.

Could we at least scan through incoming ahelps and just remove such characters before passing them to the msay panel's code?

[PJB3005]

@Shadowmech88 I mean I guess you could yeah but that's still hideous.

[PJB3005]

If anybody's interested in doing that, just wrap the text sent to the msay panel in strict_ascii(text) to remove non 7-bit ASCII values.
