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 Devanagari 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 Devanagari code order. # # Control character mappings are not shown in this table, following # the conventions of the standard UTC mapping tables. However, the # Mac OS Devanagari character set uses the standard control characters # at 0x00-0x1F and 0x7F. # # Notes on Mac OS Devanagari: # --------------------------- # # 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 Devanagari is based on IS 13194:1991 (ISCII-91), with the # addition of several punctuation and symbol characters. However, # Mac OS Devanagari does not support the ATR (attribute) mechanism of # ISCII-91. # # 1. ISCII-91 features in Mac OS Devanagari 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 DEVANAGARI OM # (U+0950) 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 Devanagari supports this mechanism, but # does not currently map any of these two-byte code points to # anything. # # 2. Mac OS Devanagari additions # # Mac OS Devanagari adds characters using the code points # 0x80-0x8A and 0x90-0x91 (the latter are some Devanagari additions # from Unicode). # # 3. Unused code points # # The following code points are currently unused, and are not shown # here: 0x8B-0x8F, 0x92-0xA0, 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 Devanagari text - 0xA1, 0xA6, 0xA7, 0xAA, 0xDB, 0xDC, 0xDF, # 0xE8, or 0xEA - 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 # Devanagari 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. # # 3. Additional loose mappings from Unicode # # These are not preserved in roundtrip mappings. # # U+0958 0xB3+0xE9 # DEVANAGARI LETTER QA # U+0959 0xB4+0xE9 # DEVANAGARI LETTER KHHA # U+095A 0xB5+0xE9 # DEVANAGARI LETTER GHHA # U+095B 0xBA+0xE9 # DEVANAGARI LETTER ZA # U+095C 0xBF+0xE9 # DEVANAGARI LETTER DDDHA # U+095D 0xC0+0xE9 # DEVANAGARI LETTER RHA # U+095E 0xC9+0xE9 # DEVANAGARI LETTER FA # # 4. Roundtrip considerations when mapping to decomposed Unicode # # Both ISCII-91 (hence Mac OS Devanagari) and Unicode provide multiple # ways of representing certain Devanagari consonants. For example, # DEVANAGARI LETTER NNNA can be represented in Unicode as the single # character 0x0929 or as the sequence 0x0928 0x093C; similarly, this # consonant can be represented in Mac OS Devanagari as 0xC7 or as the # sequence 0xC6 0xE9. This leads to some roundtrip problems. First # note that we have the following mappings without such problems: # # ISCII/ standard decomposition of reverse mapping # Mac OS Unicode mapping standard mapping of decomposition # ------ ----------------------- ---------------- ---------------- # 0xC6 0x0928 ... LETTER NA 0x0928 (same) 0xC6 # 0xCD 0x092F ... LETTER YA 0x092F (same) 0xCD # 0xCF 0x0930 ... LETTER RA 0x0930 (same) 0xCF # 0xD2 0x0933 ... LETTER LLA 0x0933 (same) 0xD2 # 0xE9 0x093C ... SIGN NUKTA 0x093C (same) 0xE9 # # However, those mappings above cause roundtrip problems for the # the following mappings if they are decomposed: # # ISCII/ standard decomposition of reverse mapping # Mac OS Unicode mapping standard mapping of decomposition # ------ ----------------------- ---------------- ---------------- # 0xC7 0x0929 ... LETTER NNNA 0x0928 0x093C 0xC6 0xE9 # 0xCE 0x095F ... LETTER YYA 0x092F 0x093C 0xCD 0xE9 # 0xD0 0x0931 ... LETTER RRA 0x0930 0x093C 0xCF 0xE9 # 0xD3 0x0934 ... LETTER LLLA 0x0933 0x093C 0xD2 0xE9 # # One solution is to use a grouping transcoding hint with the four # decompositions above to mark the decomposed sequence for special # treatment in transcoding. This yields the following mappings to # decomposed Unicode: # # ISCII/ decomposed # Mac OS Unicode mapping # ------ ---------------- # 0xC7 0xF860 0x0928 0x093C # 0xCE 0xF860 0x092F 0x093C # 0xD0 0xF860 0x0930 0x093C #
