How do I make Thunderbird automatically mark as spam all emails which have any emoji characters in subject line?

Question

This year I've started receiving spam emails which are very easily identified by containing emoji symbols in the subject title. I tried filtering them one by one, but the spammers just keep using new ones, so I'm having to constantly add more filters of a single emoji symbol. Is there a way to add all emojis to the filter, existing and planned? Or can I whitelist only alphanumeric characters and characters of certain languages I expect to receive emails in, to achieve basically the same result?
