Thanks for posting this in the Canvas Community!
I know that in the past, Synergy and other similar sis integrations would sometimes not sync over if there were Emoji's in the assignment title. I ran into a few issues where that was the case, a few years ago. Synergy might have changed this recently to allow for them to sync over. This would be a great question for your Synergy rep. I am curious about this also because I remember this being a thing a few years ago. I can't seem to find anything on this now for some reason...If you would not mind letting us know what you find on this, that would be fantastic!
