I'm having a problem with my installation regrading the use of accented characters (actually it appears with any non-ascii character). I suspect perhaps a DB setup error, though I cannot determine what it is, or how I would fix it.
If I use a non-ascii character on a page it displays fine, so long as it is not followed by further text (that is, if followed by a blank or newline). As soon as the character is followed by another character it becomes corrupted.
The page I am trying is: http://wiki.disemia.com/Sandbox It has the corrupted data in it, the pretext and posttext both should be a ü.
I took the same source (before corruption) and tried at the mediawiki sandbox and had no problems (likely eliminating browser error).
Using wget I got the contents of that page and see that the first ü's are encoded correctly for UTF-8 (C3 BC), the corrupted ü is encoded as (EF BF BD).
According to RELEASE-NOTES I am using MediaWiki 1.11.0
