In some browsers, you see the character  somewhere in your forum, often in the upper left. This is a UTF-8 "Byte Order Mark". It got into one of your forum files when somebody editted and saved that file while editing in UTF-8 mode Microsoft editors are often blamed for adding this mark at the beginning of files.
To solve this problem:
- Figure out which files have recently been edited
- One by one, open them in ANSI mode, not in UTF-8 mode (the mark may be hidden if you open the file in UTF-8 mode)
- Each time you find a file that begins with this character,
- If your editor has an option to save the file without the Byte Order Mark, use this option to save the file. In many cases, this will fix the problem.
- If the above option does not work, edit in ANSI-only mode, remove the mark, and save.
- If you need to edit the file in UTF-8 mode, use an editor which will allow you to "save without Byte Order Mark"
