Version: 1.13.1 (using 4.4.1 (KDE 4.4.1), Kubuntu packages) Compiler: cc OS: Linux (x86_64) release 2.6.31-20-generic I have received mail from someone whose first name is Pádraig (the second letter is 'a' with an acute accent). When I sort messages by sender, I expect his messages to appear between 'org-action-request@...' and 'Patrick...'. Instead, they appear between 'Price Cut ...' and 'Quidco'. KMail seems to treat a-acute as if it were later in the alphabet than any unaccented letter. The KMail message list displays Pádraig's name correctly. The 'From:' line in the SMTP header looks like this: From: =?ISO-8859-1?Q?P=E1draig_Brady?= <[Email address masked]> So KMail interprets the 'From:' line correctly; it merely sorts accented characters wrongly. I'm currently using the default settings from the United Kingdom locale. Let me take this opportunity to thank you for your hard work on KDE and its applications.
Thank you for taking the time to file a bug report. KMail2 was released in 2011, and the entire code base went through significant changes. We are currently in the process of porting to Qt5 and KF5. It is unlikely that these bugs are still valid in KMail2. We welcome you to try out KMail 2 with the KDE 4.14 release and give your feedback.
