[pkg-gnupg-maint] Bug#826405: --with-colons output is not forced to UTF-8 in error messages

[Enrico Zini]

Package: gnupg
Version: 1.4.20-6
Severity: normal

Hello,

thank you for maintaining gnupg.

The documentation of --with-colons says:

       --with-colons
              Print key listings delimited by colons. Note that the output will be encoded in UTF-8 regardless of
              any  --display-charset  setting.  This format is useful when GnuPG is called from scripts and other
              programs as it is easily machine parsed. The details of this format  are  documented  in  the  file
              ‘doc/DETAILS’, which is included in the GnuPG source distribution.

However, given a file with a bad signature, I still need
--display-charset utf-8 to get utf-8 output regardless of locale:

   $ cat /tmp/foo
