Copying non-ASCII text from Creator to TextEdit results in mojibake

Copying non-ASCII text from a text editor in Creator and pasting this text into TextEdit results in garbage (UTF-8 bytes shown as Latin-1). Copying the text inside Creator editors works fine. Copying the text from TextEdit to Creator works fine too.

Copying the text from QTextEdit inside a Qt application works fine, so that seems to be a Creator specific problem.

I cannot reproduce this problem on Linux.
