Special characters in mail messed up

Whenever I send with special characters (äöü), they arrive really broken on the other side. That’s quiteee… bad for me, since it’s really unprofessional etc. Any idea how I can fix that?

edit: äöü looks like this: äöü

Anyone encountered this too?

Yes, German Umlauts are totally messed up in Mail 2.1.0 on NC 25.0.1 You can’t actually read any messages anymore, so I quit using it. it started some days ago, so in my case it applies to reading mails in all folders. Didn’t dare to use the mail app for sending anything anymore while I am waiting for a bug fix. NC Mail is still the best looking and most promising webmail, though, in my view
