Doesn't recognize "utf8"

[forivall]

For some reason (I think it's gnome's fault), my system's locale is en_US.utf8. The following regex should detect both utf8 and UTF-8: /\butf-?8\b/i (found when grepping my system trying to figure out where it's set; it's part of an old perl module).

The following line in gnome shows both UTF-8 and utf8 (more strictly) being accepted: https://github.com/GNOME/gnome-desktop/blob/0e2f15588a89230e60a7dfe9f4164a8c17baa733/libgnome-desktop/gnome-languages.c#L91

And I think you should use the same regex for LC_CTYPE. It follows the same syntax as the other facets, so it does include the language.

I have the same issue here. Arch Linux seems to use the lowercase variant of the locale. Have not been able to track down why (looks like Gentoo does the same thing).

localectl man pages even reference the .utf8 variant so I think it may be a valid.

This should be fixed as of 2.0.1.
