What happens when you try and search for it? Does it match
"s"? (I'm pretty sure the accented characters match the unaccented
versions.)

Oops... as it was a copy of a song with altered ID3 tags, I've already
erased it...
But, yes, I'd expect it to match an 's'. I know that åäöü matches aaou
and I have a few accented n's, i's and e's that match their base
character too.
