Strange character appended to posts

Hi,

I was wondering if anyone’s experienced a strange character being appended to the end of certain pages. This is a new 2.03 install I did. If I edit that page I see it permananetly added to teh page, but if I delete it it comes back. It looks like a [] (box) in IE but a black rhombus with a questionmark in Mozilla.

It’s: ?

Any clues? Thanks!
