Fonttools pyftall subsetting + ttf woff woff2 converter

#!/bin/bash

# Convert all TTF files in the current directory using pyftsubset
# Creates subsetted versions in TTF, WOFF, and WOFF2 formats
# Usage: ./pyftall.sh [format] [options]
# format: ttf (default), woff, woff2, or all
# Any additional options will be passed to pyftsubset

# You can also add any additional parameters for pyftsubset after the format option:

# pyftall woff2 --unicodes=U+0000-04FF --with-zopfli

# Make sure fonttools is installed pip install fonttools
# add to zsh: echo 'alias pyftall="~/bin/.pyftall.sh"' >> ~/.zshrc
