Justoverclock yup, that should work; the current implementation should also work, but I see that other extension developers are still using
app.translator.locale which doesn't seem to be valid anymore as it returns undefined. I'll have to look into that when I have some time this week 🙂 We can also modify different language support in one of three ways:
1). Use the default locale set for the forum.
2). Use the user set locale preference or document cookie when the language drop-down is available.
3). Use hCaptcha's auto language detection.
I like the third approach for those forums that don't have a language pack option available in their respective language yet.
Edit: I saw your PR a few mins ago @Justoverclock, though, I would still like to know your thoughts as well about what I mentioned above 😉
