[systemd-devel] Additional Locale Variables for Units and Number Format

[Mantas Mikulėnas]

It sounds like you're reinventing LC_NUMERIC.

The locale system has a lot more than just LANG; it already allows the
number format to be overridden separately from the "language". Take a look
at `locale -k LC_NUMERIC` and <
https://pubs.opengroup.org/onlinepubs/009695399/basedefs/xbd_chap07.html>.

Adding custom variables would require changing a lot – I guess the main
consumers are libc (Glibc) and libstdc++ (GCC), but of course there are
many places which set the existing LC_* and expect things to change
accordingly, or which might implement the standard interfaces on their own
without using libc.
