--- Comment #3 from Stefan Dösinger <stefandoesin...@gmx.at> --- I start to believe that this is actually an aarch64 vs x86_64 difference. On aarch64, kmail believes the "ö" character is valid to send in headers. If I save the email as a file, the ö is encoded as ISO-8859-1 with character value 0xF6. On x86_64, it is properly escaped. Other extended characters get escaped properly. If I add some Hebrew character to my name, the From like has the RFC 2047 coding. Some other headers, like "X-KMail-Identity-Name:" or the subject are not affected. Is it possible there's a signed vs unsigned char bug somewhere? That's the most obvious difference between x86 and arm I can think of here... I updated my installation to pull in the accessibility libraries. This did not fix the problem. -- You are receiving this mail because: You are watching all bug changes.
