On a technical note, CSS doesn't actually have a problem with the accents themselves, the cause of the issue is that the links are URL-encoded, so when the string comparison looks at User:Elent%C3%A1ri_of_the_Stars and User:Elentári_of_the_Stars, and doesn't find a match - which is why it's easiest to just copy the URL if there's an extended character involved, as ΜΖD suggested.
