"""
|
|
Simple module to allow fetching unicode.org emoji lists and printing a
|
|
Python-like tuple out of them.
|
|
|
|
May not be accurate 100%, and is definitely not as efficient as it could be,
|
|
but it should only be ran whenever the Unicode consortium decides to add
|
|
new emojies to the list.
