[Sugesstion] Add Server Side Language Support

Being able to check through code what language a player is using server side and being able to use lang files for easy mutli lingual support for server side related things like commands could be very beneficial. If a player doesn’t have fabric installed of course there would have to be something to default to so a default_language entry in the fabric.mod.json could be used for that to select what language to default to. For example:

{
  "default_language": "en_us"
}

would default to English.

Having support of this level would allow developers to do a lot more with their server side mods, for example if it could be checked through code server side a mod developer could use that to:

1. Automatically translate messages from other languages to the language you have selected in your settings.
2. Add a prefix next to your name with the language you speak so other players know.
3. Make chat rooms for each language and put you in your selected language by default.

and whatever else they’d like to do with that functionality.

There is a fundamental problem with your proposal.

The translation functionality of minecraft is not available on the dedicated server. i.e. The relevant minecraft classes are not in the server jar shipped by mojang.

Also, the language files themselves are stored in resource packs which never get processed by the server.

For server side translations for mods, Server Translation API exists
