Forum OpenACS Q&A: Re: Mysterious characters appearing: A-circumflex, A-tilde

Maybe they are "gremlins" (as defined by barebones software). Gremlins are strange characters that often appear when moving/transfering text between different character standards, such as ascii, utf, iso etc; or in the case of file transfers, such as between platform standards such as apple and mswindows.

best wishes for identifying and quashing the culprit originating characters! =)
