Had a new one today CLE-EWR

"May I have your attention please -- we could use a little help here -- if there is anyone onboard who is able to speak Farsi, please ring your flight attendant call button...."

Unfortunately it seems no one did (and Google Translate doesn't list it as an option, at least on my phone) but it made me wonder... does UA have any procedures/tools for helping non-English speaking pax in these cases? This was before we pushed back but what about in the air, e.g. if there was some urgent/emergency to communicate?

Obviously on language qualified flights there's at least one FA that speaks the destination language but This isn't one of those routes...

Anyway idle question while sitting in the penalty box...
