Hey, 
I found an error - surely not an wikipedia problem, but a HTML- or browser-problem:
When using Opera quicksearch (typing "w <<keyword>>") and typing special characters, such as german äöü 
(very often used in german language) or french é (for example) - it is displayed as an rectangle - and the 
search will have no result.

I created a very simple PHP-debug once for my webpages (wikipedia is in PHP, right ?):
[PHP]
$_GET['search'] = preg_replace("'" . chr(195) . "(.)'e", "chr(ord(\\1) + 64)", $_GET['search']);
[/PHP]

would be great if you plug this little peace in yout code - its not only me in germany (or surely in the 
world) having this "problem"
