[pmwiki-users] another utf 8 question

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
