Outputs a list of any special unicode symbols used in the html document This can then be fed to a tool like pyftsubset to trim a font to only include used glyphs
use like: symbolswinger icons.html
Note: If you can Purge the css before running this it will be much much faster (not that it's slow )
Currently supports unicode charactors in css contents blocks and in hexidecimal html entities eg: supports both local file and http/https url css links
<span> ༀ</span>The name is a riff on glyphhanger which is a much more complex tool that this aims to emulate the basic features. glyphhanger doesn't work well on linux for me and has a pretty crazy looking method of extracting glyphs which involves starting a webserver and injecting javascript into the html document.
