Bug#833052: lintian: mojibake in shown overrides

[Jakub Wilk <jwilk@debian.org>]

Package: lintian
Version: 2.5.45

init-system-helpers has a Lintian override with non-ASCII UTF-8 
characters:

$ isutf8 /usr/share/lintian/overrides/init-system-helpers && echo yes
yes
$ head -n2 /usr/share/lintian/overrides/init-system-helpers
# The upstream command is called “systemctl reenable”, so we cannot just
# rename it to “re-enable” :).


Lintian turns these characters into question marks:

$ lintian --show-overrides -T spelling-error-in-manpage init-system-helpers_1.42_all.deb
N: The upstream command is called ???systemctl reenable???, so we cannot just
N: rename it to ???re-enable??? :).
O: init-system-helpers: spelling-error-in-manpage usr/share/man/man1/deb-systemd-helper.1p.gz reenable re-enable
N: The upstream command is called ???systemctl reenable???, so we cannot just
N: rename it to ???re-enable??? :).
O: init-system-helpers: spelling-error-in-manpage usr/share/man/man1/deb-systemd-helper.1p.gz reenable re-enable
