I just fixed a function named RemoveEmojis that would strip emoji characters. The problem was that emojis were still being detected in the output, even though you could open the string and clearly see it was "plaintext."

I suddenly realized the code must only be removing one part of some of the surrogate emojis, leaving behind an invisible non-printing part of an emoji in the string.

Some emojis got so complex they literally scrapped them this year. The family emojis seemed cool in someone's head, but then someone tried to make a family with mixed-ethnic parents and the children are locked to one skin color; the only solution presented was to add 7,000 more emojis to Unicode.
