Perl v5.28 updates to Unicode 10. There are 8,518 new characters, 7,473 which are in the CJK extension. There are 56 new emojis. And, the Bitcoin symbol, ₿. It adds a T. rex, 🦖, but we’re still waiting for a raptor. To Perl they are just characters like any other so you don’t need anything new to deal with them.
Perl v5.26 updates itself to Unicode 9. That’s not normally exciting news but people have been pretty enthusiastic about the 72 new emojis that come. As far as Perl cares, they are just valid code points like all of the other ones.
