Rewrite lcoale maping

[utsav0209]

Is it possible to map multiple languages to same translation file?

e.g.

{
   "fr-EN": "fr",
   "fr-US": "fr",
}

I am using next.js@10 and LTS of next-i18next.

I believe you're looking for locale fallbacks. Please check previous issues like #1465 for more information. In short, you should be able to achieve this purely through your i18next configuration.

@isaachinman the issue mentions at the end that fallbackLang is not working as expected, I tried it myself and I can confirm its not working with. Do you have any idea if there is any another way to do this?
