However, the # Mac OS Thai character set uses the standard control characters at # 0x00-0x1F and 0x7F. # # Notes on Mac OS Thai: # --------------------- # # This is a legacy Mac OS encoding; in the Mac OS X Carbon and Cocoa # environments, it is only supported via transcoding to and from # Unicode. # # 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. # ################## 0x0000 - 0x007E = 0x00 - 0x00A0 = 0xA0 0x00A9 = 0xFB 0x00AB = 0x80 0x00AE = 0xFA 0x00BB = 0x81 0x0E01 = 0xA1 0x0E02 = 0xA2 0x0E03 = 0xA3 0x0E04 = 0xA4 0x0E05 = 0xA5 0x0E06 = 0xA6 0x0E07 = 0xA7 0x0E08 = 0xA8 0x0E09 = 0xA9 0x0E0A = 0xAA 0x0E0B = 0xAB 0x0E0C = 0xAC 0x0E0D = 0xAD 0x0E0E = 0xAE 0x0E0F = 0xAF 0x0E10 = 0xB0 0x0E11 = 0xB1 0x0E12 = 0xB2 0x0E13 = 0xB3 0x0E14 = 0xB4 0x0E15 = 0xB5 0x0E16 = 0xB6 0x0E17 = 0xB7 0x0E18 = 0xB8 0x0E19 = 0xB9 0x0E1A = 0xBA 0x0E1B = 0xBB 0x0E1C = 0xBC 0x0E1D = 0xBD 0x0E1E = 0xBE 0x0E1F = 0xBF 0x0E20 = 0xC0 0x0E21 = 0xC1 0x0E22 = 0xC2 0x0E23 = 0xC3 0x0E24 = 0xC4 0x0E25 = 0xC5 0x0E26 = 0xC6 0x0E27 = 0xC7 0x0E28 = 0xC8 0x0E29 = 0xC9 0x0E2A = 0xCA 0x0E2B = 0xCB 0x0E2C = 0xCC 0x0E2D = 0xCD 0x0E2E = 0xCE 0x0E2F = 0xCF 0x0E30 = 0xD0 0x0E31 = 0x92 0x0E31 = 0xD1 0x0E32 = 0xD2 0x0E33 = 0xD3 0x0E34 = 0x94 0x0E34 = 0xD4 0x0E35 = 0x95 0x0E35 = 0xD5 0x0E36 = 0x96 0x0E36 = 0xD6 0x0E37 = 0x97 0x0E37 = 0xD7 0x0E38 = 0xD8 0x0E39 = 0xD9 0x0E3A = 0xDA 0x0E3F = 0xDF 0x0E40 = 0xE0 0x0E41 = 0xE1 0x0E42 = 0xE2 0x0E43 = 0xE3 0x0E44 = 0xE4 0x0E45 = 0xE5 0x0E46 = 0xE6 0x0E47 = 0x93 0x0E47 = 0xE7 0x0E48 = 0x83 0x0E48 = 0x88 0x0E48 = 0x98 0x0E48 = 0xE8 0x0E49 = 0x84 0x0E49 = 0x89 0x0E49 = 0x99 0x0E49 = 0xE9 0x0E4A = 0x85 0x0E4A = 0x8A 0x0E4A = 0x9A 0x0E4A = 0xEA 0x0E4B = 0x86 0x0E4B = 0x8B 0x0E4B = 0x9B 0x0E4B = 0xEB 0x0E4C = 0x87 0x0E4C = 0x8C 0x0E4C = 0x9C 0x0E4C = 0xEC 0x0E4D = 0x8F 0x0E4D = 0xED 0x0E4F = 0xEF 0x0E50 = 0xF0 0x0E51 = 0xF1 0x0E52 = 0xF2 0x0E53 = 0xF3 0x0E54 = 0xF4 0x0E55 = 0xF5 0x0E56 = 0xF6 0x0E57 = 0xF7 0x0E58 = 0xF8 0x0E59 = 0xF9 0x200B = 0xDC 0x2013 = 0xDD 0x2014 = 0xDE 0x2018 = 0x9D 0x2019 = 0x9E 0x201C = 0x8D 0x201D = 0x8E 0x2022 = 0x91 0x2026 = 0x82 0x2060 = 0xDB 0x2122 = 0xEE END_MAP
