url title

[eluser]wemago[/eluser]
is there any function / helper that
makes a string like this safe for url?

$string = 'André Começa Agrão';

if i save it using url_title() it will
kill the letters e,c and a...i'll get something
like this 'andr comea agro'.

my question is if exists a function to convert those
letters to normal letters, safe for url title.

thanx
