--- Comment #2 from Stefan Dösinger <stefandoesin...@gmx.at> --- I think some of my understanding of what triggers the bug is wrong: I tried setting up my email account in a fresh Linux user on the amd64 system: The result is that the umlaut in the "From: " and "To :" fields are properly =?UTF-8? escaped. So that it works there has nothing to do with my year old grown config. Other than the CPU architecture, the other difference I could spot is that the x86_64 system had accessibility libraries enabled (gentoo +accessibility use flag), whereas the arm64 system did not. I am changing that on the arm64 system now and will report back. It doesn't seem to have an effect on akonadi and kmail specifically, but it does affect Qt. Other things I tested and I am convinced have no effect: * Wayland vs X11 * The language (english vs german) that is active when setting up the email account -- You are receiving this mail because: You are watching all bug changes.
