Find fonts which can show a specified character and preview them in browser.

This is port from my early python script called which_fonts_support, but with some improvements:

  • ๐Ÿ›ก๏ธ Write in Rust, without unsafe. Safety
  • ๐Ÿš€๏ธ Mmap to load font file. Fast
  • ๐Ÿš€๏ธ Only parse font table we need, not all bytes of font file. Faster
  • ๐Ÿ–ฅ Support preview in terminal and browser. Friendly

Install or Update
