Helix has support for multiple languages, and you can easily leverage this system for use in your own schema, plugins, etc. Languages will be loaded from the schema and any plugins in languages/sh_languagename.lua, where languagename is the id of a language (english for English, french for French, etc). The structure of a language file is a table of phrases with the key as its phrase ID and the value as its translation for that language. For example, in plugins/area/sh_english.lua:

LANGUAGE = {
    area = "Area",
    areas = "Areas",
    areaEditMode = "Area Edit Mode",
    -- etc.
}

The phrases defined in these language files can be used with the L global function:

print(L("areaEditMode"))
> Area Edit Mode

All phrases are formatted with string.format, so if you wish to add some info in a phrase you can use standard Lua string formatting arguments:

print(L("areaDeleteConfirm", "Test"))
> Are you sure you want to delete the area "Test"?

Phrases are also usable on the server, but only when trying to localize a phrase based on a client's preferences. The server does not have a set language. An example:

Entity(1):ChatPrint(L("areaEditMode"))
> -- "Area Edit Mode" will print in the player's chatbox
