        <pre>Here I am on a fully working Ubuntu 16.04 LTS and ordinarily I get no warning
$ env|grep LANG
LANG=en_US.UTF-8
$ fc-match sans
DejaVuSans.ttf: "DejaVu Sans" "Book"

But if I mimic having no locales :

$ export LANG=UTF-8
$ fc-match sans
Fontconfig warning: ignoring UTF-8: not a valid region tag
DejaVuSans.ttf: "DejaVu Sans" "Book"

So in other words if you don't install any locales on the system, fontconfig
will issue this error.

This came up in a minimal new install used for some testing.
Perhaps a setting of UTF-8 should be silently ignored but
a conclusion that fontconfig should always warn in this situation is
fine by me, but I'd at least like to document it.</pre>
