Search only supports ASCII

Please extend search I am unable to find songs with ä ö ü ß in them, when typing the full song name in the search bar.

Small correction I can search songs with ß, but I can 100% not search ü, typing "behüte mich" despite accidentaly having this song already 3 times added to my library, because I thought I didn't had it.

Which WorshipTools app are you using?

The issue is present in Planning and Charts, typing u instead of ü shows the song I'm lookin for.
