Emoji Extractor Plus ➕
Everyone
Usage ⚒
- Clone this repo
- If you're using virtualenv, make a new env
- Run
python3 -m pip install -r requirements.pip - Run
python3 extract.py
This will extract the PNGs from the font file at /System/Library/Fonts/Apple Color Emoji.ttc. If you want to target another font file, just use the --ttc_file flag with the path to the file.
The script will save the PNG data from the font into the ./images directory wherever you ran the script. The following resolutions are curretly extracted:
- 160x160
- 96x96
- 64x64
- 52x52
- 48x48
- 40x40
- 32x32
- 26x26
- 20x20
All the emojis will be labeled with their proper names, too!
Fun Info
Unicode is awesome 💥
Making this script was a fun exercise in learning more about Unicode and how it's being used to scale the number and types of emojis that Apple is making these days. With the addition of skin tones and gender modifiers, emoji are no longer one Unicode character anymore.
To give an example of one of the more complicated emojis that Apple has created, take \U0001f468\u200d\U0001f469\u200d\U0001f467\u200d\U0001f467. (Shown as represented in Python)
This string is broken into several characters:
\U0001f468: \U0001f469: \U0001f467:
Each character has a \u200d character between it, which is a zero width joiner in between it. This character is used to join two or more Unicode characters together, in this case the people in the emoji. the ZWG is used also for any modifier, such as skin tone and gender.
My experience before this exercise was mostly with characters that were in the ASCII table from the olden days, so exploring this topic with emojis was interesting. Unicode was created to scale to many more characters than could be represented in the ASCII table, which allows it to support not only emojis, but all writing systems.
