Formatting problems when copy and paste withing emClient

International characters (such as åäö) gets transformed into “åäö” if I first type them in a new email message, and then copy and paste them within eMclient.
If I instead paste the string into a notepad and then copy the same string before pasting it back into eMclient it comes back as it should.

I can also copy texts from the subject line and paste it directly into a new email’s text without loosing the formatting.

I didn’t have these problems in earlier versions of eMclient. Now I am on 7.0.26687.0.
