Some Chinese characters can not be extracted correctly.

Bug report

• A description of the bug
  With CMAP installed, the output file remained containing Chinese characters as raw cid code (CID:xxx).
  While debuging, I found that PDFPageInterpreter.fontmap['F3'].cid2unicode a dictionary of 200+ items which is obviously not long enough.
  Hope it helps!
