GitHub font preview

A userscript that adds a font file preview

• This script adds the ability to preview fonts & glyphs.
• Currently ony OpenType (otf), TrueType (ttf) and Web Open (woff; not woff2) font formats are supported.
• opentype.js is used for font rendering and the preview code has been blatantly copied from the font inspector and glyph inspector demos (Copyright © 2015 Frederik De Bleser; MIT license).
• Click this link to install from GitHub, or install from GreasyFork.
• After installing, try the userscript on one of these pages:
  • Font-Awesome
  • material-design-iconic-font
  • Google fonts
  • FontSquirrel fonts
  • Hack
  • Adobe source-code-pro
  • ionicons
