I was trawling through my spam folder (which I rarely do, because Gmail rarely has false positives) and I noticed something interesting:
Something like over half of the messages have at least one animated emoji in the subject.
None of my friends would use that crap. No valid company that I'd do business with would ever do that either.
How can I create a filter to, perhaps, auto-delete messages with animated emoji in the subject?
Using jamesmstone's clue below, I tried a search with
subject:"=?UTF-8?" and several other permutations, but none worked.
Here's a sample set of headers from one of these steaming piles:
