See how Python 3.4 embarassingly fails this extremely simple
RFC2047 eMail header MIME encoding test: the resulting header
line is 82 chars, and thus longer than what RFC822 permits.
“Embarassing” because PHP gets it all right.
If I add another ' foo' at the end, I get this:
pöstal foo bar baz foo bar baz foo bar baz foo bar baz foo
Subject:
=?iso-8859-1?q?p=F6stal_foo_bar_baz_foo_bar_baz_foo_bar_baz_foo_bar_baz_foo?=
“Double embarassing” because even Python 2.7 got that one
not as catastrophically wrong.
This is bad because MUAs like Pine rightfully refuse to
RFC2047-decode such bad and broken messages (but apparently
widespread to an amount that Alpine as packaged in Debian
contains a hack to allow for such broken, overlong lines).
