title: Extract Font Glyphs
body: <p>I have this problem across my mind, any help will be appreciated.
  Is there are PHP function, or library that can extract some glyphs form a font file?</p>
  
  <p>Edit:
  By means to extract some glyphs, I wanted to create a new font file based on the glyphs extracted (so it has smaller bytes), or just get the glyphs and create base64 encoded font data from it so I can embed it via @font-face. I just wanted to get rid glyphs that has no use so CSS (base64) or font file will be loaded faster.</p>
