Missing locales on Arch Linux guest

[AshkanArabim]

Describe the bug I have a clean installation of the Arch Linux guest (with an Arch Linux host) that I've installed using toolbox create gnome (I plan to use it for some Gnome development). When I enter the machine to install the fa_IR locale by uncommenting it from /etc/locale.gen and running sudo locale-gen, I get this message:

[ashkan@toolbox gnome-clocks-new]$ sudo locale-gen
Generating locales...
  en_US.UTF-8... done
  fa_IR.UTF-8...[error] cannot open locale definition file `fa_IR': No such file or directory

I assume this is related to the fact that fa_IR isn't listed when I run ls /usr/share/i18n/locales/. There are many locales missing here when I compare it to my host OS.

Steps how to reproduce the behaviour

1. Get an Arch Linux host and install toolbox. (or manually create the Arch container in the next step using the --distro flag)
2. Create a container: toolbox create <name> and enter it with toolbox enter <name>
3. Uncomment the line with fa_IR in /etc/locale.gen and save.
4. Run sudo locale-gen

Expected behaviour For sudo locale-gen to successfully generate the Persian locale; with an output like this:

Generating locales...
  en_US.UTF-8... done
  fa_IR.UTF-8... done
Generation complete.

Actual behaviour It fails to generate the Persian locale (fa_IR).
