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. # ################## 0x00 - 0x7E = 0x0000 - 0x80 = 0x00AB 0x81 = 0x00BB 0x82 = 0x2026 0x83 = 0x0E48 0x84 = 0x0E49 0x85 = 0x0E4A 0x86 = 0x0E4B 0x87 = 0x0E4C 0x88 = 0x0E48 0x89 = 0x0E49 0x8A = 0x0E4A 0x8B = 0x0E4B 0x8C = 0x0E4C 0x8D = 0x201C 0x8E = 0x201D 0x8F = 0x0E4D 0x91 = 0x2022 0x92 = 0x0E31 0x93 = 0x0E47 0x94 = 0x0E34 0x95 = 0x0E35 0x96 = 0x0E36 0x97 = 0x0E37 0x98 = 0x0E48 0x99 = 0x0E49 0x9A = 0x0E4A 0x9B = 0x0E4B 0x9C = 0x0E4C 0x9D = 0x2018 0x9E = 0x2019 0xA0 = 0x00A0 0xA1 = 0x0E01 0xA2 = 0x0E02 0xA3 = 0x0E03 0xA4 = 0x0E04 0xA5 = 0x0E05 0xA6 = 0x0E06 0xA7 = 0x0E07 0xA8 = 0x0E08 0xA9 = 0x0E09 0xAA = 0x0E0A 0xAB = 0x0E0B 0xAC = 0x0E0C 0xAD = 0x0E0D 0xAE = 0x0E0E 0xAF = 0x0E0F 0xB0 = 0x0E10 0xB1 = 0x0E11 0xB2 = 0x0E12 0xB3 = 0x0E13 0xB4 = 0x0E14 0xB5 = 0x0E15 0xB6 = 0x0E16 0xB7 = 0x0E17 0xB8 = 0x0E18 0xB9 = 0x0E19 0xBA = 0x0E1A 0xBB = 0x0E1B 0xBC = 0x0E1C 0xBD = 0x0E1D 0xBE = 0x0E1E 0xBF = 0x0E1F 0xC0 = 0x0E20 0xC1 = 0x0E21 0xC2 = 0x0E22 0xC3 = 0x0E23 0xC4 = 0x0E24 0xC5 = 0x0E25 0xC6 = 0x0E26 0xC7 = 0x0E27 0xC8 = 0x0E28 0xC9 = 0x0E29 0xCA = 0x0E2A 0xCB = 0x0E2B 0xCC = 0x0E2C 0xCD = 0x0E2D 0xCE = 0x0E2E 0xCF = 0x0E2F 0xD0 = 0x0E30 0xD1 = 0x0E31 0xD2 = 0x0E32 0xD3 = 0x0E33 0xD4 = 0x0E34 0xD5 = 0x0E35 0xD6 = 0x0E36 0xD7 = 0x0E37 0xD8 = 0x0E38 0xD9 = 0x0E39 0xDA = 0x0E3A 0xDB = 0x2060 0xDC = 0x200B 0xDD = 0x2013 0xDE = 0x2014 0xDF = 0x0E3F 0xE0 = 0x0E40 0xE1 = 0x0E41 0xE2 = 0x0E42 0xE3 = 0x0E43 0xE4 = 0x0E44 0xE5 = 0x0E45 0xE6 = 0x0E46 0xE7 = 0x0E47 0xE8 = 0x0E48 0xE9 = 0x0E49 0xEA = 0x0E4A 0xEB = 0x0E4B 0xEC = 0x0E4C 0xED = 0x0E4D 0xEE = 0x2122 0xEF = 0x0E4F 0xF0 = 0x0E50 0xF1 = 0x0E51 0xF2 = 0x0E52 0xF3 = 0x0E53 0xF4 = 0x0E54 0xF5 = 0x0E55 0xF6 = 0x0E56 0xF7 = 0x0E57 0xF8 = 0x0E58 0xF9 = 0x0E59 0xFA = 0x00AE 0xFB = 0x00A9 END_MAP
