+#
+#   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

+# 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.
