International (swedish) characters in FT search

I’m trying to make my Domino web server to find documents with a search string containing swedish (åäö) characters. Right now, it doesn’t.

I have already set notes.ini to FT_Index_Accent_Sens=1, but that didn’t make any difference.

Do I have to install the swedish language pack for this to work? Any other suggestions are more than welcome!
