Incorrect text conversion Mac → iOS

With DEVONthink ed 3.5 all my text notes, when synced to iPad have incorrect character mapping. Swedish characters å, ä, ö. Å, Ä and Ö all converts to garbage when reading the document. However, if I tap “Edit” button (iPad) the textstring converts to correct form. Exiting Edit mode, pressing Done, and the string reverts back to garbage.

What kind of text notes? Plain text? If yes, would you mind sharing such a note with us by email to support (at)
