APPENDIX D                                               Character Sets and Encodings



ZapfDingbats (ITC Zapf Dingbats) font programs, which are among the standard
14 predefined fonts. These fonts have built-in encodings that are unique to each
font. (The characters for ZapfDingbats are ordered by code instead of by name,
since the names in that font are meaningless.)

                         TABLE D.1 Latin-text encodings
ENCODING             DESCRIPTION

StandardEncoding     Adobe standard Latin-text encoding. This is the built-in encoding
                     defined in Type 1 Latin-text font programs (but generally not in
                     TrueType font programs). PDF does not have a predefined encod-
                     ing named StandardEncoding. However, it is useful to describe
                     this encoding, since a font’s built-in encoding can be used as the
                     base encoding from which differences are specified in an encod-
                     ing dictionary.

MacRomanEncoding     Mac OS standard encoding for Latin text in Western writing sys-
                     tems. PDF has a predefined encoding named MacRomanEncoding
                     that can be used with both Type 1 and TrueType fonts.

WinAnsiEncoding      Windows Code Page 1252, often called the “Windows ANSI”
                     encoding. This is the standard Windows encoding for Latin text
                     in Western writing systems. PDF has a predefined encoding
                     named WinAnsiEncoding that can be used with both Type 1 and
                     TrueType fonts.

PDFDocEncoding       Encoding for text strings in a PDF document outside the docu-
                     ment’s content streams. This is one of two encodings (the other
                     being Unicode) that can be used to represent text strings; see Sec-
                     tion , “Text String Type.” PDF does not have a predefined encod-
                     ing named PDFDocEncoding; it is not customary to use this
                     encoding to show text from fonts.

MacExpertEncoding    An encoding for use with expert fonts—ones containing the
                     expert character set. PDF has a predefined encoding named
                     MacExpertEncoding. Despite its name, it is not a platform-specific
                     encoding; however, only certain fonts have the appropriate char-
                     acter set for use with this encoding. No such fonts are among the
                     standard 14 predefined fonts.
