[TYPO3-english] cooluri - problems with umlauts by manual updating

hey jan,

I tried it with this:
if (function_exists('iconv')) return iconv('ISO-8859-1', 
'ASCII//TRANSLIT', $s);

the result of this quick fix is, that the umlaut (f.e. ö) will converted 
in "-" and not in "oe".

it's better than cropped but do you have any idea to optimize it?

thanx!
