I'm having a small problem.

I would like to see the finnish letter "ä" transformed into an "a" and the finnish letter "ö" transformed into an "o" in the URL of my forum posts. Now it just cuts those letters off and the URL looks a bit weird if those letters are used (which is quite often).

For example I have a discussion called "Onko nettideittailu vieläkään hyväksyttävää nykypäivänä?" which shows in the URL as "/onko-nettideittailu-vielkn-hyvksyttv-nykypivn/". Here's the live example (hope you see all the letters correctly): http://otamut.org/keskustelu/discussion/5/onko-nettideittailu-vielkn-hyvksyttv-nykypivn/

How could I fix this?

And while we're at it, danish too. (æøå)

I think this list cover the Scandinavian languages? Or am I missing somewhing?

å = a
ä = a
ö = o
æ = a
ø = o

Here is the current function used to encode the url titles (found in library/framework/framework.functions.php):

function CleanupString($InString) {
$Code = explode(',', '<,>,',&,",À,Á,Â,Ã,Ä,Ä,Å,Ā,Ą,Ă,Æ,Ç,Ć,Č,Ĉ,Ċ,Ď,Đ,Ð,È,É,Ê,Ë,Ē,Ę,Ě,Ĕ,Ė,Ĝ,Ğ,Ġ,Ģ,Ĥ,Ħ,Ì,Í,Î,Ï,Ī,Ĩ,Ĭ,Į,İ,IJ,Ĵ,Ķ,Ł,Ľ,Ĺ,Ļ,Ŀ,Ñ,Ń,Ň,Ņ,Ŋ,Ò,Ó,Ô,Õ,Ö,Ö,Ø,Ō,Ő,Ŏ,Œ,Ŕ,Ř,Ŗ,Ś,Š,Ş,Ŝ,Ș,Ť,Ţ,Ŧ,Ț,Ù,Ú,Û,Ü,Ū,Ü,Ů,Ű,Ŭ,Ũ,Ų,Ŵ,Ý,Ŷ,Ÿ,Ź,Ž,Ż,Þ,Þ,à,á,â,ã,ä,ä,å,ā,ą,ă,æ,ç,ć,č,ĉ,ċ,ď,đ,ð,è,é,ê,ë,ē,ę,ě,ĕ,ė,ƒ,ĝ,ğ,ġ,ģ,ĥ,ħ,ì,í,î,ï,ī,ĩ,ĭ,į,ı,ij,ĵ,ķ,ĸ,ł,ľ,ĺ,ļ,ŀ,ñ,ń,ň,ņ,ʼn,ŋ,ò,ó,ô,õ,ö,ö,ø,ō,ő,ŏ,œ,ŕ,ř,ŗ,š,ù,ú,û,ü,ū,ü,ů,ű,ŭ,ũ,ų,ŵ,ý,ÿ,ŷ,ž,ż,ź,þ,ß,ſ,А,Б,В,Г,Д,Е,Ё,Ж,З,И,Й,К,Л,М,Н,О,П,Р,С,Т,У,Ф,Х,Ц,Ч,Ш,Щ,Ъ,Ы,Э,Ю,Я,а,б,в,г,д,е,ё,ж,з,и,й,к,л,м,н,о,п,р,с,т,у,ф,х,ц,ч,ш,щ,ъ,ы,э,ю,я');

Impressive list of characters :)

Yep, it should work...

I'm not great with the inner workings of character encodings, but I know that there are a few other members on here who are - I'm hoping one or two of them will join in on the discussion...
