New submission from Jonathan Horn <jonathan.hor...@googlemail.com>: I encountered a problem with replacing the 'Subject' header of an email. After serializing it again, the utf8 encoding was wrong. It seems to be occurring when folding the internal header objects.
Example: >> email.policy.default.fold_binary('Subject', >> email.policy.default.header_store_parse('Subject', 'Hello Wörld! Hello >> Wörld! Hello Wörld! Hello Wörld!Hello Wörld!')[1]) Expected output: b'Subject: Hello =?utf-8?q?W=C3=B6rld!_Hello_W=C3=B6rld!_Hello_W=C3=B6rld!?=\n Hello =?utf-8?q?W=C3=B6rld!Hello_W=C3=B6rld!?=\n' (or similar) Actual output: b'Subject: Hello =?utf-8?q?W=C3=B6rld!_Hello_W=C3=B6rld!_Hello_W=C3=B6rld!?=\n Hello =?utf-8?=?utf-8?q?q=3FW=3DC3=3DB6rld!Hello=3F=3D_W=C3=B6rld!?=\n' I'm running Python 3.7.3 on Arch Linux using Linux 5.0. ---------- components: email messages: 339419 nosy: Jonathan Horn, barry, r.david.murray priority: normal severity: normal status: open title: Email header folded incorrectly type: behavior versions: Python 3.7 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue36520> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
