One of my villagers commented in a rather excited way about eating a “???”. Specifically, here is their full comment (with the red underline)
The only available food at the time were berries, turnips, pumpkins, and I think racoon jerky. No idea what that particular villager was eating as I didn’t notice the weirdness of the message until everyone had finished eating.
This was in 64-bit version of build 2148.
