Alphabets/Foreign language filters
A way for streamers and moderators to filter foreign languages in chat, and different alphabets.
As an experienced moderator for large streamers on Twitch, one of the most common "rule-breakers" are the ones speaking in a foreign language. Usually larger streamers who are English spoken wants to have their chat 100% English, therefore a filter for foreign languages outside of the English alphabet would be really helpful. As there are no current tools to really moderate foreign languages. This could be done by making a filter for characters outside of the English alphabet, such as Chinese, Japanese, Arabic, Russian,
etc.
Obviously this wouldn't affect people using the English alphabet, but it will definitely reduce the amount of "rule-breakers" inform of speaking a different language than allowed in chat. This would also significantly help moderators for larger streamers who has an "open chat", and usually not in sub-mode.
