|
|
# Usage:
|
|
|
|
|
# 1. Download all emoji
|

|
|
|

|
|
#
|
|
|
|
|
# Notes:
|
|
|
|
|
# * You'll need a emoji font like "Noto Emoji" or "EmojiOne".
|
|
|
|
|
# * Confirming an item will automatically paste it WITHOUT
|
|
|
|
|
# writing it to your clipboard.
|
|
|
|
|
# * Ctrl+C will copy it to your clipboard WITHOUT pasting it.
