title: How to generate font file with Unicode support for three.js?
body: <p>I am testing three.js TextGeometry elements with text containing non-Latin glyphs, such as Cyrillic and Chinese glyphs, using the Helvetiker typeface. </p>
  
  <p>The rendered test elements contain question marks in place of non-Latin characters, presumably because Helvetiker only includes some subset of Latin characters.</p>
  
  <p>I'd like to make a replacement for Helvetiker. How are TTF typefaces rendered into JS equivalents, so that I could test taking an open-source typeface and including the glyph sets I am interested in, and render text in three.js?</p>
