       1. In PDF 1.3, the euro character was added to the Adobe standard Latin character set. It
          is encoded as 200 in WinAnsiEncoding and 240 in PDFDocEncoding, assigning codes
          that were previously unused. Apple changed the Mac OS Latin-text encoding for code
          333 from the currency character to the euro character. However, this incompatible
          change has not been reflected in PDF’s MacRomanEncoding, which continues to map
          code 333 to currency. If the euro character is desired, an encoding dictionary can be
          used to specify this single difference from MacRomanEncoding.
       2. In PDF 1.3, the existing Zcaron and zcaron characters were added to WinAnsiEncoding
          as the previously unused codes 216 and 236.
       3. In WinAnsiEncoding, all unused codes greater than 40 map to the bullet character.
          However, only code 225 is specifically assigned to the bullet character; other codes are
          subject to future reassignment.
       4. The character names guillemotleft and guillemotright are misspelled. The correct spell-
          ing for this punctuation character is guillemet. However, the misspelled names are the
          ones actually used in the fonts and encodings containing these characters.
       5. The hyphen character is also encoded as 255 in WinAnsiEncoding. The meaning of this
          duplicate code is “soft hyphen,” but it is typographically the same as hyphen.
       6. The space character is also encoded as 312 in MacRomanEncoding and as 240 in
          WinAnsiEncoding. This duplicate code signifies a nonbreaking space; it is typographi-
          cally the same as space.
