Emoji were always part of Unicode proper, some of them (e.g. the 
snowman) even way before they were called emoji. What changed between 
Unicode 12 and Unicode 13 is the location of some of the property data 
files in the data published by Unicode. That may have motivated Perl's 
change in implementation between these two versions.

[I know this because I'm in charge of the Ruby side of things; I have 
yet to update to Unicode 13.0, and the change in file location is one of 
the items on my plate.]
