#

#   Apple, the Apple logo, and Macintosh are trademarks of Apple

#   Computer, Inc., registered in the United States and other countries.

#   Unicode is a trademark of Unicode Inc. For the sake of brevity,

#   throughout this document, 'Macintosh' can be used to refer to

#   Macintosh computers and 'Unicode' can be used to refer to the

#   Unicode standard.

#

#   Apple makes no warranty or representation, either express or

#   implied, with respect to these tables, their quality, accuracy, or

#   fitness for a particular purpose. In no event will Apple be liable

#   for direct, indirect, special, incidental, or consequential damages 

#   resulting from any defect or inaccuracy in this document or the

#   accompanying tables.

#

#   These mapping tables and character lists are subject to change.

#   The latest tables should be available from the following:

#

#   <http://www.unicode.org/Public/MAPPINGS/VENDORS/APPLE/>

#

#   For general information about Mac OS encodings and these mapping

#   tables, see the file 'README.TXT'.

#

# Format:

# -------

#

#   Three tab-separated columns;

#   '#' begins a comment which continues to the end of the line.

#     Column #1 is the Mac OS Symbol code (in hex as 0xNN)

#     Column #2 is the corresponding Unicode or Unicode sequence

#       (in hex as 0xNNNN or 0xNNNN+0xNNNN).

#     Column #3 is a comment containing the Unicode name.

#       In some cases an additional comment follows the Unicode name.

#

#   The entries are in Mac OS Symbol code order.

#

#   Some of these mappings require the use of corporate characters.

#   See the file 'CORPCHAR.TXT' and notes below.

#

#   Control character mappings are not shown in this table, following

#   the conventions of the standard UTC mapping tables. However, the

#   Mac OS Symbol character set uses the standard control characters

#   at 0x00-0x1F and 0x7F.

#

# Notes on Mac OS Symbol:

# -----------------------

#

#   The Mac OS Symbol encoding shares the script code smRoman

#   (0) with the Mac OS Roman encoding. To determine if the Symbol

#   encoding is being used, you must check if the font name is

#   'Symbol'.

#

#   Before Mac OS 8.5, code point 0xA0 was unused. In Mac OS 8.5

#   and later versions, code point 0xA0 is EURO SIGN and maps to

#   U+20AC (the Symbol font is updated for Mac OS 8.5 to reflect

#   this).

#

#   The layout of the Mac OS Symbol character set is identical to

#   the layout of the Adobe Symbol encoding vector, with the

#   addition of the Apple logo character at 0xF0.

#

#   This character set encodes a number of glyph fragments. Some are

#   used as extenders: 0x60 is used to extend radical signs, 0xBD and

#   0xBE are used to extend vertical and horizontal arrows, etc. In

#   addition, there are top, bottom, and center sections for

#   parentheses, brackets, integral signs, and other signs that may

#   extend vertically for 2 or more lines of normal text. As of

#   Unicode 3.2, most of these are now encoded in Unicode; a few are

#   not, so these are mapped using corporate-zone Unicode characters

#   (see below).

#

#   In addition, Symbol separately encodes both serif and sans-serif

#   forms for copyright, trademark, and registered signs. Unicode

#   encodes only the abstract characters, so one set of these (the

#   sans-serif forms) are also mapped using corporate-zone Unicode

#   characters (see below).

#

#   The following code points are unused, and are not shown here:

#   0x80-0x9F, 0xFF.

#

# Unicode mapping issues and notes:

# ---------------------------------

#

#   The goals in the mappings provided here are:

#   - Ensure roundtrip mapping from every character in the Mac OS

#     Symbol character set to Unicode and back

#   - Use standard Unicode characters as much as possible, to

#     maximize interchangeability of the resulting Unicode text.

#     Whenever possible, avoid having content carried by private-use

#     characters.

#

#   Some of the characters in the Mac OS Symbol character set do not

#   correspond to distinct, single Unicode characters. To map these

#   and satisfy both goals above, we employ various strategies.

#

#   a) If possible, use private use characters in combination with

#   standard Unicode characters to mark variants of the standard

#   Unicode character.

#

#   Apple has defined a block of 32 corporate characters as 'transcoding

#   hints.' These are used in combination with standard Unicode characters

#   to force them to be treated in a special way for mapping to other

#   encodings; they have no other effect. Sixteen of these transcoding

#   hints are 'grouping hints' - they indicate that the next 2-4 Unicode

#   characters should be treated as a single entity for transcoding. The

#   other sixteen transcoding hints are 'variant tags' - they are like

#   combining characters, and can follow a standard Unicode (or a sequence

#   consisting of a base character and other combining characters) to

#   cause it to be treated in a special way for transcoding. These always

#   terminate a combining-character sequence.

#

#   The transcoding coding hint used in this mapping table is the variant

#   tag 0xF87F. Since this is combined with standard Unicode characters,

#   some characters in the Mac OS Symbol character set map to a sequence

#   of two Unicodes instead of a single Unicode character.

#

#   For example, the Mac OS Symbol character at 0xE2 is an alternate,

#   sans-serif form of the REGISTERED SIGN (the standard mapping is for

#   the abstract character at 0xD2, which here has a serif form). So 0xE2

#   is mapped to 0x00AE (REGISTERED SIGN) + 0xF87F (a variant tag).

#

#   b) Otherwise, use private use characters by themselves to map

#   Mac OS Symbol characters which have no relationship to any standard

#   Unicode character.

#

#   The following additional corporate zone Unicode characters are

#   used for this purpose here:

#

#     0xF8E5  radical extender

#     0xF8E6  vertical arrow extender

#     0xF8FF  Apple logo

#

#   NOTE: The graphic image associated with the Apple logo character

#   is not authorized for use without permission of Apple, and

#   unauthorized use might constitute trademark infringement.

#

# Details of mapping changes in each version:

# -------------------------------------------

#

#   Changes from version b02 to version b03/c01:

#

#   - Update mappings for encoded glyph fragments 0xBE, 0xE6-EF, 0xF4,

#     0xF6-FE to use new Unicode 3.2 characters instead of using either

#     single corporate-use characters (e.g. 0xBE was mapped to 0xF8E7) or

#     sequences combining a standard Unicode character with a transcoding

#     hint (e.g. 0xE6 was mapped to 0x0028+0xF870).

#

#   Changes from version n05 to version b02:

#

#   - Encoding changed for Mac OS 8.5; 0xA0 now maps to 0x20AC, EURO

#   SIGN. 0xA0 was unmapped in earlier versions.

#

#   Changes from version n03 to version n05:

#

#       - Change strict mapping for 0xE1 & 0xF1 from U+2329 & U+232A

#     to their canonical decompositions, U+3008 & U+3009.

#

#   - Change mapping for the following to use standard Unicode +

#     transcoding hint, instead of single corporate-zone

#     character: 0xE2-0xE4, 0xE6-0xEE, 0xF4, 0xF6-0xFE.
