In some cases an additional comment follows the # Unicode name(s). # # The entries are in two sections. The first section is for pairs of # Mac OS Gujarati code points that must be mapped in a special way. # The second section maps individual code points. # # Within each section, the entries are in Mac OS Gujarati code order. # # Control character mappings are not shown in this table, following # the conventions of the standard UTC mapping tables. However, the # Mac OS Gujarati character set uses the standard control characters # at 0x00-0x1F and 0x7F. # # Notes on Mac OS Gujarati: # ------------------------- # # 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. # # Mac OS Gujarati is based on IS 13194:1991 (ISCII-91), with the # addition of several punctuation and symbol characters. However, # Mac OS Gujarati does not support the ATR (attribute) mechanism of # ISCII-91. # # 1. ISCII-91 features in Mac OS Gujarati include: # # a) Overloading of nukta # # In addition to using the nukta (0xE9) like a combining dot below, # nukta is overloaded to function as a general character modifier. # In this role, certain code points followed by 0xE9 are treated as # a two-byte code point representing a character which may be # rather different than the characters represented by either of # the code points alone. For example, the character GUJARATI OM # (U+0AD0) is represented in ISCII-91 as candrabindu + nukta. # # b) Explicit halant and soft halant # # A double halant (0xE8 + 0xE8) constitutes an "explicit halant", # which will always appear as a halant instead of causing formation # of a ligature or half-form consonant. # # Halant followed by nukta (0xE8 + 0xE9) constitutes a "soft # halant", which prevents formation of a ligature and instead # retains the half-form of the first consonant. # # c) Invisible consonant # # The byte 0xD9 (called INV in ISCII-91) is an invisible consonant: # It behaves like a consonant but has no visible appearance. It is # intended to be used (often in combination with halant) to display # dependent forms in isolation, such as the RA forms or consonant # half-forms. # # d) Extensions for Vedic, etc. # # The byte 0xF0 (called EXT in ISCII-91) followed by any byte in # the range 0xA1-0xEE constitutes a two-byte code point which can # be used to represent additional characters for Vedic (or other # extensions); 0xF0 followed by any other byte value constitutes # malformed text. Mac OS Gujarati supports this mechanism, but # does not currently map any of these two-byte code points to # anything. # # 2. Mac OS Gujarati additions # # Mac OS Gujarati adds characters using the code points # 0x80-0x8A and 0x90. # # 3. Unused code points # # The following code points are currently unused, and are not shown # here: 0x8B-0x8F, 0x91-0xA0, 0xAB, 0xAF, 0xC7, 0xCE, 0xD0, 0xD3, # 0xE0, 0xE4, 0xEB-0xEF, 0xFB-0xFF. In addition, 0xF0 is not shown # here, but it has a special function as described above. # # Unicode mapping issues and notes: # --------------------------------- # # 1. Mapping the byte pairs # # If one of the following byte values is encountered when mapping # Mac OS Gujarati text - xA1, xAA, xDF, or 0xE8 - then the next # byte (if there is one) should be examined. If the next byte is # 0xE9 - or also 0xE8, if the first byte was 0xE8 - then the byte # pair should be mapped using the first section of the mapping # table below. Otherwise, each byte should be mapped using the # second section of the mapping table below. # # - The Unicode Standard, Version 2.0, specifies how explicit # halant and soft halant should be represented in Unicode; # these mappings are used below. # # If the byte value 0xF0 is encountered when mapping Mac OS # Gujarati text, then the next byte should be examined. If there # is no next byte (e.g. 0xF0 at end of buffer), the mapping # process should indicate incomplete character. If there is a next # byte but it is not in the range 0xA1-0xEE, the mapping process # should indicate malformed text. Otherwise, the mapping process # should treat the byte pair as a valid two-byte code point with no # mapping (e.g. map it to QUESTION MARK, REPLACEMENT CHARACTER, # etc.). # # 2. Mapping the invisible consonant # # It has been suggested that INV in ISCII-91 should map to ZERO # WIDTH NON-JOINER in Unicode. However, this causes problems with # roundtrip fidelity: The ISCII-91 sequences 0xE8+0xE8 and 0xE8+0xD9 # would map to the same sequence of Unicode characters. We have # instead mapped INV to LEFT-TO-RIGHT MARK, which avoids these # problems. # # Details of mapping changes in each version: # ------------------------------------------- # ################## BEGIN_MAP 0x00 - 0x7F = 0x0000 - 0x80 = 0x00D7 0x81 = 0x2212 0x82 = 0x2013 0x83 = 0x2014 0x84 = 0x2018 0x85 = 0x2019 0x86 = 0x2026 0x87 = 0x2022 0x88 = 0x00A9 0x89 = 0x00AE 0x8A = 0x2122 0x90 = 0x0965 0xA1 = 0x0A81 #0xA1+0xE9 = 0x0AD0 0xA2 = 0x0A82 0xA3 = 0x0A83 0xA4 = 0x0A85 0xA5 = 0x0A86 0xA6 = 0x0A87 0xA7 = 0x0A88 0xA8 = 0x0A89 0xA9 = 0x0A8A 0xAA = 0x0A8B #0xAA+0xE9 = 0x0AE0 0xAC = 0x0A8F 0xAD = 0x0A90 0xAE = 0x0A8D 0xB0 = 0x0A93 0xB1 = 0x0A94 0xB2 = 0x0A91 0xB3 = 0x0A95 0xB4 = 0x0A96 0xB5 = 0x0A97 0xB6 = 0x0A98 0xB7 = 0x0A99 0xB8 = 0x0A9A 0xB9 = 0x0A9B 0xBA = 0x0A9C 0xBB = 0x0A9D 0xBC = 0x0A9E 0xBD = 0x0A9F 0xBE = 0x0AA0 0xBF = 0x0AA1 0xC0 = 0x0AA2 0xC1 = 0x0AA3 0xC2 = 0x0AA4 0xC3 = 0x0AA5 0xC4 = 0x0AA6 0xC5 = 0x0AA7 0xC6 = 0x0AA8 0xC8 = 0x0AAA 0xC9 = 0x0AAB 0xCA = 0x0AAC 0xCB = 0x0AAD 0xCC = 0x0AAE 0xCD = 0x0AAF 0xCF = 0x0AB0 0xD1 = 0x0AB2 0xD2 = 0x0AB3 0xD4 = 0x0AB5 0xD5 = 0x0AB6 0xD6 = 0x0AB7 0xD7 = 0x0AB8 0xD8 = 0x0AB9 0xD9 = 0x200E 0xDA = 0x0ABE 0xDB = 0x0ABF 0xDC = 0x0AC0 0xDD = 0x0AC1 0xDE = 0x0AC2 0xDF = 0x0AC3 #0xDF+0xE9 = 0x0AC4 0xE1 = 0x0AC7 0xE2 = 0x0AC8 0xE3 = 0x0AC5 0xE5 = 0x0ACB 0xE6 = 0x0ACC 0xE7 = 0x0AC9 0xE8 = 0x0ACD #0xE8+0xE8 = 0x0ACD+0x200C #0xE8+0xE9 = 0x0ACD+0x200D 0xE9 = 0x0ABC 0xEA = 0x0964 0xF1 = 0x0AE6 0xF2 = 0x0AE7 0xF3 = 0x0AE8 0xF4 = 0x0AE9 0xF5 = 0x0AEA 0xF6 = 0x0AEB 0xF7 = 0x0AEC 0xF8 = 0x0AED 0xF9 = 0x0AEE 0xFA = 0x0AEF END_MAP
