In some cases an additional comment follows the 62# Unicode name(s). 63# 64# The entries are in two sections. The first section is for pairs of 65# Mac OS Devanagari code points that must be mapped in a special way. 66# The second section maps individual code points. 67# 68# Within each section, the entries are in Mac OS Devanagari code order. 69# 70# Control character mappings are not shown in this table, following 71# the conventions of the standard UTC mapping tables. However, the 72# Mac OS Devanagari character set uses the standard control characters 73# at 0x00-0x1F and 0x7F. 74# 75# Notes on Mac OS Devanagari: 76# --------------------------- 77# 78# This is a legacy Mac OS encoding; in the Mac OS X Carbon and Cocoa 79# environments, it is only supported via transcoding to and from 80# Unicode. 81# 82# Mac OS Devanagari is based on IS 13194:1991 (ISCII-91), with the 83# addition of several punctuation and symbol characters. However, 84# Mac OS Devanagari does not support the ATR (attribute) mechanism of 85# ISCII-91. 86# 87# 1. ISCII-91 features in Mac OS Devanagari include: 88# 89# a) Overloading of nukta 90# 91# In addition to using the nukta (0xE9) like a combining dot below, 92# nukta is overloaded to function as a general character modifier. 93# In this role, certain code points followed by 0xE9 are treated as 94# a two-byte code point representing a character which may be 95# rather different than the characters represented by either of 96# the code points alone. For example, the character DEVANAGARI OM 97# (U+0950) is represented in ISCII-91 as candrabindu + nukta. 98# 99# b) Explicit halant and soft halant 100# 101# A double halant (0xE8 + 0xE8) constitutes an "explicit halant", 102# which will always appear as a halant instead of causing formation 103# of a ligature or half-form consonant. 104# 105# Halant followed by nukta (0xE8 + 0xE9) constitutes a "soft 106# halant", which prevents formation of a ligature and instead 107# retains the half-form of the first consonant. 108# 109# c) Invisible consonant 110# 111# The byte 0xD9 (called INV in ISCII-91) is an invisible consonant: 112# It behaves like a consonant but has no visible appearance. It is 113# intended to be used (often in combination with halant) to display 114# dependent forms in isolation, such as the RA forms or consonant 115# half-forms. 116# 117# d) Extensions for Vedic, etc. 118# 119# The byte 0xF0 (called EXT in ISCII-91) followed by any byte in 120# the range 0xA1-0xEE constitutes a two-byte code point which can 121# be used to represent additional characters for Vedic (or other 122# extensions); 0xF0 followed by any other byte value constitutes 123# malformed text. Mac OS Devanagari supports this mechanism, but 124# does not currently map any of these two-byte code points to 125# anything. 126# 127# 2. Mac OS Devanagari additions 128# 129# Mac OS Devanagari adds characters using the code points 130# 0x80-0x8A and 0x90-0x91 (the latter are some Devanagari additions 131# from Unicode). 132# 133# 3. Unused code points 134# 135# The following code points are currently unused, and are not shown 136# here: 0x8B-0x8F, 0x92-0xA0, 0xEB-0xEF, 0xFB-0xFF. In addition, 137# 0xF0 is not shown here, but it has a special function as described 138# above. 139# 140# Unicode mapping issues and notes: 141# --------------------------------- 142# 143# 1. Mapping the byte pairs 144# 145# If one of the following byte values is encountered when mapping 146# Mac OS Devanagari text - 0xA1, 0xA6, 0xA7, 0xAA, 0xDB, 0xDC, 0xDF, 147# 0xE8, or 0xEA - then the next byte (if there is one) should be 148# examined. If the next byte is 0xE9 - or also 0xE8, if the first 149# byte was 0xE8 - then the byte pair should be mapped using the 150# first section of the mapping table below. Otherwise, each byte 151# should be mapped using the second section of the mapping table 152# below. 153# 154# - The Unicode Standard, Version 2.0, specifies how explicit 155# halant and soft halant should be represented in Unicode; 156# these mappings are used below. 157# 158# If the byte value 0xF0 is encountered when mapping Mac OS 159# Devanagari text, then the next byte should be examined. If there 160# is no next byte (e.g. 0xF0 at end of buffer), the mapping 161# process should indicate incomplete character. If there is a next 162# byte but it is not in the range 0xA1-0xEE, the mapping process 163# should indicate malformed text. Otherwise, the mapping process 164# should treat the byte pair as a valid two-byte code point with no 165# mapping (e.g. map it to QUESTION MARK, REPLACEMENT CHARACTER, 166# etc.). 167# 168# 2. Mapping the invisible consonant 169# 170# It has been suggested that INV in ISCII-91 should map to ZERO 171# WIDTH NON-JOINER in Unicode. However, this causes problems with 172# roundtrip fidelity: The ISCII-91 sequences 0xE8+0xE8 and 0xE8+0xD9 173# would map to the same sequence of Unicode characters. We have 174# instead mapped INV to LEFT-TO-RIGHT MARK, which avoids these 175# problems. 176# 177# 3. Additional loose mappings from Unicode 178# 179# These are not preserved in roundtrip mappings. 180# 181# U+0958 0xB3+0xE9 # DEVANAGARI LETTER QA 182# U+0959 0xB4+0xE9 # DEVANAGARI LETTER KHHA 183# U+095A 0xB5+0xE9 # DEVANAGARI LETTER GHHA 184# U+095B 0xBA+0xE9 # DEVANAGARI LETTER ZA 185# U+095C 0xBF+0xE9 # DEVANAGARI LETTER DDDHA 186# U+095D 0xC0+0xE9 # DEVANAGARI LETTER RHA 187# U+095E 0xC9+0xE9 # DEVANAGARI LETTER FA 188# 189# 4. Roundtrip considerations when mapping to decomposed Unicode 190# 191# Both ISCII-91 (hence Mac OS Devanagari) and Unicode provide multiple 192# ways of representing certain Devanagari consonants. For example, 193# DEVANAGARI LETTER NNNA can be represented in Unicode as the single 194# character 0x0929 or as the sequence 0x0928 0x093C; similarly, this 195# consonant can be represented in Mac OS Devanagari as 0xC7 or as the 196# sequence 0xC6 0xE9. This leads to some roundtrip problems. First 197# note that we have the following mappings without such problems: 198# 199# ISCII/ standard decomposition of reverse mapping 200# Mac OS Unicode mapping standard mapping of decomposition 201# ------ ----------------------- ---------------- ---------------- 202# 0xC6 0x0928 ...
