title: Finding out what characters a given font supports
body: <p>How do I extract the list of supported Unicode characters from a TrueType or embedded OpenType font on Linux?</p>
  
  <p>Is there a tool or a library I can use to process a .ttf or a .eot file and build a list of code points (like U+0123, U+1234, etc.) provided by the font?</p>
