Bug #339657 fixed the problem where bts wouldn't properly escape 8bit
characters in DEBFULLNAME. But if DEBFULLNAME isn't set, the full name
is taken from /etc/passwd and used without escaping it first, causing
the same problems as in #339657.

Oh.  I don't know how to solve this one.

The full name is taken from DEBFULLNAME or EMAIL, and if neither of
these are set, then from getpwuid.  If `locale charmap` returns
anything, the charset is taken from that setting and is used to encode
the name for MIME purposes.

This bug arises in the following situation:

  DEBFULLNAME is not set, and
  EMAIL is either unset or does not contain the name, and
  getpwuid (reading /etc/passwd or some other source) returns a name
    using an 8-bit encoding, and
  the locale does not match the encoding of /etc/passwd or whatever

How should I determine the correct encoding to use in this situation?
Or would it be better not to use the name at all in such a situation?

The latter might be best.

I agree partially...

DEBFULLNAME was not set
EMAIL was not set
getpwuid returned my name using an 8-bit encoding (UTF-8)

...but...

the locale does match the encoding of /etc/passwd...locale charmap
returns "UTF-8".

So there seems to be something missing here.

An alternative fix would be to verify before sending any mails that
the From header does indeed not contain any 8-bit characters and warn if
it does.

That's just plain weird.  How on earth could that happen?

Agreed.

Looking at a message where it failed, the relevant header says:
From: david@2gen.com (David Härdeman)

and a message which didn't fail (with DEBFULLNAME and DEBEMAIL set):
From david@2gen.com Tue Apr 25 13:01:37 2006
...
From: David =?UTF-8?Q?H=C3=A4rdeman?= <david@2gen.com>

Ah, that's it!!  Misread the bts code.

The bug is not in bts at all, it's in mail (presumably /usr/bin/mail),
which is called if neither DEBEMAIL nor EMAIL are set.  So whichever
package you have which provides the mail executable is the one which
is sending unencoded 8-bit names.

Please could you reassign this bug to that package?

Thanks,

Ok, I've just reassigned the bug report to mailx, and I'll merge it with
207724.

Thanks for the help.
