Slightly related, once in a while I get funny emails through
git-commits-head@vger.kernel.org, where the subject is completely screwed up:

    Subject: \x64\x72\x6D\x2F\x74\x69\x6E\x79\x64\x72\x6D\x3A
\x6D\x69\x70\x69\x2D\x64\x62\x69\x3A \x53\x69\x6C\x65\x6E\x63\x65\x3A
‘\x63\x6D\x64’ \x6D\x61\x79 \x62\x65

and some of the mail headers end up in the body as well:

    =?UTF-8?Q?\x75\x73\x65\x64_\x75\x6E\x69\x6E\x69\x74\x69\x61\x6C\x69\x7A\x65\x64?=

        drm/tinydrm: mipi-dbi: Silence: ‘cmd’ may be used uninitialized

My first guess was Noralf's UTF8 last name, but after looking at a few more,
they all seem to have UTF8 quotes from gcc output in the oneline summary.

In personal conversations with technical people, I call myself a hacker. But
when I'm talking to journalists I just say "programmer" or something like that.
