When you publish a calendar to a webdav-server, umlauts and other special characters are being shreddered. When you try to edit such ics-files with a text-editor, you only get question marks instead of the umlaut / special character.
Appointment entry in Outlook: "Gespräch mit Firma xyz"
Entry in ics-file: "Gespr?ch mit Firma xyz"
I tried to convert the ics-file via iconv to iso-8859-1(5) or utf-8, but that didn't work. If I am right, this means, that the question marks are only question marks and not specially encoded characters.
A solution for this would be great!
