Font switches to symbols upon receipt of auto responder email

We are experiencing an issue with our Form called "Artisan Application" (created on Jul 29, 2016)

Several of our customers (not most, only some) have received their confirmation auto-responder email in what they describe as a "foreign language". It actually looks to me like the Font on the responder email is being switched to a "symbol" font in their Inbox. 

What can I do fix this from happening?

example attached.

Thanks in advance!

Your autoresponder is indeed setup in a different language.

Please try deleting the autoresponder, and creating it again:
