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.
