Bug#555330: lintian: manpage-has-errors-from-man does not work correctly

[Michael Meskes]

Package: lintian
Version: 2.2.17
Severity: normal

When running under locale C the test does not work correctly:

michael@feivel:~$ LANG=C man --warnings -E UTF-8 -l /usr/share/man/man8/acpid.8.gz >/dev/null
col: Invalid or incomplete multibyte or wide character
michael@feivel:~$ LANG=de_DE.UTF-8 man --warnings -E UTF-8 -l /usr/share/man/man8/acpid.8.gz >/dev/null
michael@feivel:~$

The reason seems to be that man pipes its output through col when not
displaying on a terminal and col setting the local to C which apparently does
not mean UTF-8. Therefore the unicode hyphen (e2 80 90) triggers the above
mentioned error message in col's file io.

The above usage has, however, previously worked without issues.  col was
recently upgraded to a new upstream version, which seems to be when the
issue occurred.

I'll leave this bug filed against Lintian for the moment until the situation
is clearer; #555331 is a related bug against bsdmainutils.

Regards,

Adam
