I was editing my errors.log to pull the TGFT guild meeting minutes , and I noticed a huge ( many thousands) repeated block of :

')
CTextDraw warning: trying to display character 245 0xf5 ('�')
CTextDraw warning: trying to display character 145 0x91 ('�')
CTextDraw warning: trying to display character 11 0x0b ('

Not a clue . But I did have a big lag spike , so if it helps fix things , good .

os 10.6

That happens when the interface displays a text character that the font doesn't have a glyph for. It will generate the error message every frame or few until the character is not in the interface anymore.

Hmm. Mine was doing this too earlier today but not the last time i ran VO. Maybe something from the IRC relay or a plugin?
