0010-set-language.patch forces UTF-8 into use in ~/.pam_environment

[Teemu Toivola]

The modification done by 0010-set-language.patch (see LP: #866062) cause UTF-8 to be forced in ~/.pam_environment even if something else has been defined in /etc/default/locale.

Example:
/etc/default/locale contains:
LANG="en_US"

After login from lightdm ~/.pam_environment contains:
LANG=en_US.UTF-8

and that result in UTF-8 being forced to use for example in terminals.

This problem can be traced to 0010-set-language.patch that introduces the function "user_locale_utf8_fix" that for some reason gets called every time variables are handled. As a result, it's not possible to have UTF-8 disabled.

As a very crude hack, I've modified the /usr/share/language-tools/save-to-pam-env script to call sed and remove any UTF-8 string before the exit line.

Thank you for your bug report, setting Low priority there are very few reasons to not use UTF8 nowadays

Teemu,
While I think you are right about the Ubuntu UIs generally don't support non-UTF-8 locales, it seems not to be because of the user_locale_utf8_fix() function in 0010-set-language.patch. user_locale_utf8_fix() does not convert UTF-8 locale names to non-UTF-8 names; it just replaces .utf8 with .UTF-8 to not reintroduce bug 666565.

Personally I think that in order to make Ubuntu support non-UTF-8 locales would need rather extensive changes in a bunch of packages. If that's what you want, discussing it on e.g. ubuntu-devel-discuss is probably a good idea.
