Some servers are configured to automatically prepend or append files to HTML output. This may be configured in a .htaccess, in php.ini or in httpd.conf, something like:

   php_value auto_prepend_file prepend.php
   (or auto_append_file)

If this is the case, the file that is prepended or appended should be checked too - especially if it looks like an empty file with 3 bytes.

Other than that, right now I don't see what could be the problem. It still may be related to PmWiki, to a skin, or to a recipe, and the advice for debugging is to disable one after another all recipes and every time reload the page to see if the characters have disappeared - if they have, then the last disabled recipe should be double checked.

There are many wikis running in UTF-8 without this problem (including www.pmwiki.org ), so it may be a problem specific to your specific installation.

I did a search of my directory for files with BOM, but only came up with a few pdfs.

I also opened and re-saved as utf-8 every file I could think of that I might have changed, and re-copied the latest version of pmwiki. I'm starting to get really frustrated that I can't find what is causing this.

The characters that appear on your site are 0xEF 0xBF 0xBD which is the standard Byte order mark (or mask). One of your *.php or *.tmpl files was modified and saved with BOM and it shouldn't. You should reopen it and save it in "UTF-8 without Byte Order Mark" (or "without BOM"), then upload them back to the server.

The files which come in the PmWiki core distribution don't have Byte order marks. I don't know of any recipe which comes with a BOM. If I were you, I'd first look at the files which you have modified yourself.
