Description Olav Vitters 2012-09-30 13:27:15 CEST

Description of problem:
I just imported hitori. I used the spec file from Fedora.

In the description Fedora used the following UTF-8 character: Ã. This looks like an 'x' but is actually different. It is a mathematics characters (10x10 => 10Ã10).

You can enter this character by e.g.: <compose key>, <x>, <x>

The changelog mailing list has the following header:
Content-Type: text/plain; charset="iso-8859-1"

This results in the email being rendered incorrectly. Spec files should be utf-8, so the header should contain:
Content-Type: text/plain; charset="utf-8"

This also applies to (security) updates notifications as pointed out by Jake from LWN who let us know the following after the "MGASA-2016-0093: Updated openssl packages fix security vulnerabilities" announcement email was sent:

FYI, this email does not have a Content-Type header, but has
Latin1-encoded data (the Ã¤ in KÃ¤sper) ... this makes automated
ingestion difficult ... our program guesses UTF8 and barfs ... we
could, I suppose, try again with Latin1, but it would be best if your
system just told us what it was sending ...

This can cause actual mail delivery failures too. Before this fix meant that the mail was malformed and contained no subject and other nice things...
