Wow, very impressive! ... agree with kcott that it deserves its own CUFP page.

I played briefly with your command on Ubuntu using perl v5.38: 

~/pm/Tux$ perl -CEO -wE'say "\x{1F468}\x{1F3FD}\x{200D}\x{2708}\x{FE0F}"'
👨🏽‍✈️

~/pm/Tux$ echo -e '\U1F468\U1F3FD\U200D\U2708\UFE0F'
👨🏽‍✈️

AFAICT, the output from the perl -CEO and the bash echo -e commands above is identical, namely:

Running this command produced useful output (that seems to match yours), despite the error messages: 

~/pm/Tux$ echo -e '\U1F468\U1F3FD\U200D\U2708\UFE0F' | xargs uchar -v
Can't exec "locate": No such file or directory at ~/pm/Tux/uchar line 103.

Using CODE blocks intead of pre:
