  subset: [65, 66], // only read `a`, `b` glyf
  hinting: true, // save font hinting
  compound2simple: true, // transform ttf compound glyf to simple
  inflate: null, // inflate function for woff
  combinePath: false, // for svg path
});
var fontObject = font.get();
console.log(Object.keys(fontObject));
/* => [ 'version',
  'numTables',
  'searchRenge',

// fs.writeFileSync('font.woff', buffer);

// to base64 str
font.toBase64({
  type: 'ttf' // support ttf,woff,eot,svg
});

// optimize glyf
font.optimize()

// compound2simple
font.compound2simple()

// sort glyf
font.sort()

// find glyf
var result = font.find({
  unicode: [65]
});
var result = font.find({
  filter: function (glyf) {
