62#   These mapping tables and character lists are subject to change.
63#   The latest tables should be available from the following:

65#   <http://www.unicode.org/Public/MAPPINGS/VENDORS/APPLE/>
66#
67#   For general information about Mac OS encodings and these mapping
68#   tables, see the file "README.TXT".
69#
70# Format:
71# -------
72#
73#   Three tab-separated columns;
74#   '#' begins a comment which continues to the end of the line.
75#     Column #1 is the Mac OS Thai code (in hex as 0xNN)
76#     Column #2 is the corresponding Unicode or Unicode sequence
77#       (in hex as 0xNNNN or 0xNNNN+0xNNNN).
78#     Column #3 is a comment containing the Unicode name
79#
80#   The entries are in Mac OS Thai code order.
81#
82#   Some of these mappings require the use of corporate characters.
83#   See the file "CORPCHAR.TXT" and notes below.
84#
85#   Control character mappings are not shown in this table, following
86#   the conventions of the standard UTC mapping tables. However, the
87#   Mac OS Thai character set uses the standard control characters at
88#   0x00-0x1F and 0x7F.
89#
90# Notes on Mac OS Thai:
91# ---------------------
92#
93#   This is a legacy Mac OS encoding; in the Mac OS X Carbon and Cocoa
94#   environments, it is only supported via transcoding to and from
95#   Unicode.
96#
97#   Codes 0xA1-0xDA and 0xDF-0xFB are the character set from Thai
98#   standard TIS 620-2533, except that the following changes are
99#   made:
100#     0xEE is TRADE MARK SIGN (instead of THAI CHARACTER YAMAKKAN)
101#     0xFA is REGISTERED SIGN (instead of THAI CHARACTER ANGKHANKHU)
102#     0xFB is COPYRIGHT SIGN (instead of THAI CHARACTER KHOMUT)
103#
104#   Codes 0x80-0x82, 0x8D-0x8E, 0x91, 0x9D-0x9E, and 0xDB-0xDE are
105#   various additional punctuation marks (e.g. curly quotes,
106#   ellipsis), no-break space, and two special characters "word join"
107#   and "word break".
108#
109#   Codes 0x83-0x8C, 0x8F, and 0x92-0x9C are for positional variants
110#   of the upper vowels, tone marks, and other signs at 0xD1,
111#   0xD4-0xD7, and 0xE7-0xED. The positional variants would normally
112#   be considered presentation forms only and not characters. In most
113#   cases they are not typed directly; they are selected automatically
114#   at display time by the WorldScript software. However, using the
115#   Thai-DTP keyboard, the presentation forms can in fact be typed
116#   directly using dead keys. Thus they must be treated as real
117#   characters in the Mac OS Thai encoding. They are mapped using
118#   variant tags; see below.
119#
120#   Several code points are undefined and unused (they cannot be
121#   typed using any of the Mac OS Thai keyboard layouts): 0x90, 0x9F,
122#   0xFC-0xFE. These are not shown in the table below.
123#
124# Unicode mapping issues and notes:
125# ---------------------------------
126#
127#   The goals in the Apple mappings provided here are:
128#   - Ensure roundtrip mapping from every character in the Mac OS Thai
129#   character set to Unicode and back
130#   - Use standard Unicode characters as much as possible, to maximize
131#   interchangeability of the resulting Unicode text. Whenever possible,
132#   avoid having content carried by private-use characters.
133#
134#   To satisfy both goals, we use private use characters to mark variants
135#   that are similar to a sequence of one or more standard Unicode
136#   characters.
137#
138#   Apple has defined a block of 32 corporate characters as "transcoding
139#   hints." These are used in combination with standard Unicode characters
140#   to force them to be treated in a special way for mapping to other
141#   encodings; they have no other effect. Sixteen of these transcoding
142#   hints are "grouping hints" - they indicate that the next 2-4 Unicode
143#   characters should be treated as a single entity for transcoding. The
144#   other sixteen transcoding hints are "variant tags" - they are like
145#   combining characters, and can follow a standard Unicode (or a sequence
146#   consisting of a base character and other combining characters) to
147#   cause it to be treated in a special way for transcoding. These always
148#   terminate a combining-character sequence.
149#
150#   The transcoding coding hints used in this mapping table are four
151#   variant tags in the range 0xF873-75. Since these are combined with
152#   standard Unicode characters, some characters in the Mac OS Thai
153#   character set map to a sequence of two Unicodes instead of a single
154#   Unicode character. For example, the Mac OS Thai character at 0x83 is a
155#   low-left positional variant of THAI CHARACTER MAI EK (the standard
156#   mapping is for the abstract character at 0xE8). So 0x83 is mapped to
157#   0x0E48 (THAI CHARACTER MAI EK) + 0xF875 (a variant tag).
158#
159# Details of mapping changes in each version:
160# -------------------------------------------
161#
162#   Changes from version b02 to version b03/c01:
163#
164#   - Update mapping for 0xDB to use new Unicode 3.2 character U+2060
165#     WORD JOINER instead of U+FEFF ZERO WIDTH NO-BREAK SPACE (BOM)
166#
167#   Changes from version n04 to version n07:
168#
169#   - Changed mappings of the positional variants to use standard
170#   Unicodes + transcoding hint, instead of using single corporate
171#   zone characters. This affected the mappings for the following:
172#   0x83-08C, 0x8F, 0x92-0x9C
173#
174#   - Just comment out unused code points in the table, instead
175#   of mapping them to U+FFFD.
