I've run into an issue with (command- de- ) briefing texts: special characters come out garbled in-game.
I don't talk about really weird stuff like greek letters, but normal everday characters like ä, ö, ü and ß

You might think of those metal döts as just garnish but I guarantee you that you can't write any german sentence without them

Is this a newer FSO problem?
I've always played the Freespace main campaigns, retail or with media vps, in german and I don't recall any issues with my beloved Umlauts.
Is there a solution?
Edit: ß seems to be automatically converted to "ss". Thats fine, but I still need the Umlauts!
