Bug Description

In order to get output in English (not my local Swedish language) I ran the following alias in a terminal window

alias LC='LC_ALL=C;LANG=C'

and after that I ran

ubuntu-support-status --show-unsupported

$ LC
$ ubuntu-support-status --show-unsupported
Traceback (most recent call last):
  File "/usr/bin/ubuntu-support-status", line 145, in <module>
    print(_("Support status summary of '%s':") % os.uname()[1])
UnicodeEncodeError: 'ascii' codec can't encode character '\xf6' in position 29: ordinal not in range(128)

(I have used LC for years in several versions of Ubuntu without problems.)

The command

ubuntu-support-status --show-unsupported

works in my local language.

I bisected my LC alias:

LANG=C

provokes this bug.

LC_ALL=C

does not provoke it, but the output will still be in my native language.

Same for a German Ubuntu 16.04 LTS install and an installation pre-set to German, and it appears that the locale configuration is ignored - in the following situation, the output should be in English.

$ LC_MESSAGES=C ubuntu-support-status

Workaround: run:

env LC_ALL=C LANGUAGE= ubuntu-support-status

or

env LANGUAGE=en ubuntu-support-status

So it appears that the LANGUAGE=... variable takes precedence over LANG and LC_* although it's not a GUI application, and of course, ubuntu-support-status does not have a man page where this could be documented, and update-manager also does NOT document or reference this variable in an "ENVIRONMENT" section.
