#   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

#

#   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

#

#   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 Thai 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

#

#   The entries are in Mac OS Thai 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 Thai character set uses the standard control characters at

#   0x00-0x1F and 0x7F.

#

# Notes on Mac OS Thai:

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

#

#   Codes 0xA1-0xDA and 0xDF-0xFB are the character set from Thai

#   standard TIS 620-2533, except that the following changes are

#   made:

#     0xEE is TRADE MARK SIGN (instead of THAI CHARACTER YAMAKKAN)

#     0xFA is REGISTERED SIGN (instead of THAI CHARACTER ANGKHANKHU)

#     0xFB is COPYRIGHT SIGN (instead of THAI CHARACTER KHOMUT)

#

#   Codes 0x80-0x82, 0x8D-0x8E, 0x91, 0x9D-0x9E, and 0xDB-0xDE are

#   various additional punctuation marks (e.g. curly quotes,

#   ellipsis), no-break space, and two special characters 'word join'

#   and 'word break'.

#

#   Codes 0x83-0x8C, 0x8F, and 0x92-0x9C are for positional variants

#   of the upper vowels, tone marks, and other signs at 0xD1,

#   0xD4-0xD7, and 0xE7-0xED. The positional variants would normally

#   be considered presentation forms only and not characters. In most

#   cases they are not typed directly; they are selected automatically

#   at display time by the WorldScript software. However, using the

#   Thai-DTP keyboard, the presentation forms can in fact be typed

#   directly using dead keys. Thus they must be treated as real

#   characters in the Mac OS Thai encoding. They are mapped using

#   variant tags; see below.

#

#   Several code points are undefined and unused (they cannot be

#   typed using any of the Mac OS Thai keyboard layouts): 0x90, 0x9F,

#   0xFC-0xFE. These are not shown in the table below.

#

# Unicode mapping issues and notes:

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

#

#   The goals in the Apple mappings provided here are:

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

#   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.

#

#   To satisfy both goals, we use private use characters to mark variants

#   that are similar to a sequence of one or more standard Unicode

#   characters.

#

#   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 hints used in this mapping table are four

#   variant tags in the range 0xF873-75. Since these are combined with

#   standard Unicode characters, some characters in the Mac OS Thai

#   character set map to a sequence of two Unicodes instead of a single

#   Unicode character. For example, the Mac OS Thai character at 0x83 is a

#   low-left positional variant of THAI CHARACTER MAI EK (the standard

#   mapping is for the abstract character at 0xE8). So 0x83 is mapped to

#   0x0E48 (THAI CHARACTER MAI EK) + 0xF875 (a variant tag).

#

# Details of mapping changes in each version:

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

#

#   Changes from version b02 to version b03/c01:

#

#   - Update mapping for 0xDB to use new Unicode 3.2 character U+2060

#     WORD JOINER instead of U+FEFF ZERO WIDTH NO-BREAK SPACE (BOM)

#

#   Changes from version n04 to version n07:

#

#   - Changed mappings of the positional variants to use standard

#   Unicodes + transcoding hint, instead of using single corporate

#   zone characters. This affected the mappings for the following:

#   0x83-08C, 0x8F, 0x92-0x9C

#

#   - Just comment out unused code points in the table, instead

#   of mapping them to U+FFFD.
