Odd Comments On Tube Squad Blog

For some reason I keep getting odd comments on this blog that don't show up at all. I don't know if they're left in a language other than English, but they seems to be in characters that do not display correctly. Someone leaves a comment and all I see is Square, Square, Square, dot, dot, dot. If you are trying to contribute something positive to the commentary, great. If not, please go elsewhere, because I do moderate all comments and those that will not show up legibly will obviously be deleted.
