According to PDF reference, this field is optional. Also form the
• A font that is used to display glyphs that do not use MacRomanEncoding or
  WinAnsiEncoding should not specify an Encoding entry. The font descriptor’s
  Symbolic flag (see Table 5.20) should be set, and its font program’s “cmap” table
  should contain a (1, 0) subtable. It may also contain a (3, 0) subtable; if present,
  this subtable should map from character codes in the range 0xF000 to 0xF0FF
  by prepending the single-byte codes in the (1, 0) subtable with 0xF0 and map-
  ping to the corresponding glyph descriptions.
