Determining system language

[JavaFXpert]

I realize that minetest.setting_get('language') will return the language setting in minetest.conf, but if it's not set, then it doesn't seem to return a language code. How can a mod know the system language? Is available via an API call within Minetest?

Try os.getlocale I know setlocale exists, not sure about the counter part

Or os.getenv("LANG"), but not sure if that's portable

Thanks. os.setlocale() doesn't seem to exist, and os.getenv("LANG") doesn't seem to be portable. Minetest seems to sense the system language, so hopefully there is, or will be, some way to retrieve it.
