fonttools subset

Generate subsets of fonts or optimize file sizes. More information: https://fonttools.readthedocs.io/en/latest/subset/index.html.

• Subset a TTF font file to the Basic Latin Unicode block:

fonttools subset {{path/to/font.ttf}} --unicodes=U+0000-007F

• Change the file type to WOFF2:

fonttools subset {{path/to/font.ttf}} --unicodes=U+0000-007F --flavor=woff2

• Keep only the onum (oldstyle figures) and kern (kerning) OpenType font features:

fonttools subset {{path/to/font.ttf}} --unicodes=U+0000-007F --layout-features=onum,kern

• Set the output file's name:

fonttools subset {{path/to/font.ttf}} --unicodes=U+0000-007F --output-file={{path/to/subset.ttf}}
