No, I am using the same English keyboard that I have used since I became a member.Â This only started when I could no longer post in mod comments from the forum site.
Do you guys use non-Engish keyboards? I'm fairly sure some symbols (such as the German upside-down quotation marks) aren't supported by the current character encoding used by the forums.Â
The character is the forum saying "I have no idea what that symbol is, so here's an error character.".Â
I think this may also happen with Mac OS devices as a result of the keyboard using "smart quotes" which you can turn off in the keyboard settings.
I have always followed what I post by using "My Content".Â Now I cannot answer any post made in a mod comment that I have using "My Content". I have to lookup the post in the mod page and make a reply there.Â
And it only appears in the mod comments that are read in the forums.Â
