In some cases an additional comment follows the 66# Unicode name(s). 67# 68# The entries are in two sections. The first section is for pairs of 69# Mac OS Gujarati code points that must be mapped in a special way. 70# The second section maps individual code points. 71# 72# Within each section, the entries are in Mac OS Gujarati code order. 73# 74# Control character mappings are not shown in this table, following 75# the conventions of the standard UTC mapping tables. However, the 76# Mac OS Gujarati character set uses the standard control characters 77# at 0x00-0x1F and 0x7F. 78# 79# Notes on Mac OS Gujarati: 80# ------------------------- 81# 82# This is a legacy Mac OS encoding; in the Mac OS X Carbon and Cocoa 83# environments, it is only supported via transcoding to and from 84# Unicode. 85# 86# Mac OS Gujarati is based on IS 13194:1991 (ISCII-91), with the 87# addition of several punctuation and symbol characters. However, 88# Mac OS Gujarati does not support the ATR (attribute) mechanism of 89# ISCII-91. 90# 91# 1. ISCII-91 features in Mac OS Gujarati include: 92# 93# a) Overloading of nukta 94# 95# In addition to using the nukta (0xE9) like a combining dot below, 96# nukta is overloaded to function as a general character modifier. 97# In this role, certain code points followed by 0xE9 are treated as 98# a two-byte code point representing a character which may be 99# rather different than the characters represented by either of 100# the code points alone. For example, the character GUJARATI OM 101# (U+0AD0) is represented in ISCII-91 as candrabindu + nukta. 102# 103# b) Explicit halant and soft halant 104# 105# A double halant (0xE8 + 0xE8) constitutes an "explicit halant", 106# which will always appear as a halant instead of causing formation 107# of a ligature or half-form consonant. 108# 109# Halant followed by nukta (0xE8 + 0xE9) constitutes a "soft 110# halant", which prevents formation of a ligature and instead 111# retains the half-form of the first consonant. 112# 113# c) Invisible consonant 114# 115# The byte 0xD9 (called INV in ISCII-91) is an invisible consonant: 116# It behaves like a consonant but has no visible appearance. It is 117# intended to be used (often in combination with halant) to display 118# dependent forms in isolation, such as the RA forms or consonant 119# half-forms. 120# 121# d) Extensions for Vedic, etc. 122# 123# The byte 0xF0 (called EXT in ISCII-91) followed by any byte in 124# the range 0xA1-0xEE constitutes a two-byte code point which can 125# be used to represent additional characters for Vedic (or other 126# extensions); 0xF0 followed by any other byte value constitutes 127# malformed text. Mac OS Gujarati supports this mechanism, but 128# does not currently map any of these two-byte code points to 129# anything. 130# 131# 2. Mac OS Gujarati additions 132# 133# Mac OS Gujarati adds characters using the code points 134# 0x80-0x8A and 0x90. 135# 136# 3. Unused code points 137# 138# The following code points are currently unused, and are not shown 139# here: 0x8B-0x8F, 0x91-0xA0, 0xAB, 0xAF, 0xC7, 0xCE, 0xD0, 0xD3, 140# 0xE0, 0xE4, 0xEB-0xEF, 0xFB-0xFF. In addition, 0xF0 is not shown 141# here, but it has a special function as described above. 142# 143# Unicode mapping issues and notes: 144# --------------------------------- 145# 146# 1. Mapping the byte pairs 147# 148# If one of the following byte values is encountered when mapping 149# Mac OS Gujarati text - xA1, xAA, xDF, or 0xE8 - then the next 150# byte (if there is one) should be examined. If the next byte is 151# 0xE9 - or also 0xE8, if the first byte was 0xE8 - then the byte 152# pair should be mapped using the first section of the mapping 153# table below. Otherwise, each byte should be mapped using the 154# second section of the mapping table below. 155# 156# - The Unicode Standard, Version 2.0, specifies how explicit 157# halant and soft halant should be represented in Unicode; 158# these mappings are used below. 159# 160# If the byte value 0xF0 is encountered when mapping Mac OS 161# Gujarati text, then the next byte should be examined. If there 162# is no next byte (e.g. 0xF0 at end of buffer), the mapping 163# process should indicate incomplete character. If there is a next 164# byte but it is not in the range 0xA1-0xEE, the mapping process 165# should indicate malformed text. Otherwise, the mapping process 166# should treat the byte pair as a valid two-byte code point with no 167# mapping (e.g. map it to QUESTION MARK, REPLACEMENT CHARACTER, 168# etc.). 169# 170# 2. Mapping the invisible consonant 171# 172# It has been suggested that INV in ISCII-91 should map to ZERO 173# WIDTH NON-JOINER in Unicode. However, this causes problems with 174# roundtrip fidelity: The ISCII-91 sequences 0xE8+0xE8 and 0xE8+0xD9 175# would map to the same sequence of Unicode characters. We have 176# instead mapped INV to LEFT-TO-RIGHT MARK, which avoids these 177# problems. 178# 179# Details of mapping changes in each version: 180# ------------------------------------------- 181# 182################## 183BEGIN_MAP 1840x00 - 0x7F = 0x0000 - 1850x80 = 0x00D7 1860x81 = 0x2212 1870x82 = 0x2013 1880x83 = 0x2014 1890x84 = 0x2018 1900x85 = 0x2019 1910x86 = 0x2026 1920x87 = 0x2022 1930x88 = 0x00A9 1940x89 = 0x00AE 1950x8A = 0x2122 1960x90 = 0x0965 1970xA1 = 0x0A81 198#0xA1+0xE9 = 0x0AD0 1990xA2 = 0x0A82 2000xA3 = 0x0A83 2010xA4 = 0x0A85 2020xA5 = 0x0A86 2030xA6 = 0x0A87 2040xA7 = 0x0A88 2050xA8 = 0x0A89 2060xA9 = 0x0A8A 2070xAA = 0x0A8B 208#0xAA+0xE9 = 0x0AE0 2090xAC = 0x0A8F 2100xAD = 0x0A90 2110xAE = 0x0A8D 2120xB0 = 0x0A93 2130xB1 = 0x0A94 2140xB2 = 0x0A91 2150xB3 = 0x0A95 2160xB4 = 0x0A96 2170xB5 = 0x0A97 2180xB6 = 0x0A98 2190xB7 = 0x0A99 2200xB8 = 0x0A9A 2210xB9 = 0x0A9B 2220xBA = 0x0A9C 2230xBB = 0x0A9D 2240xBC = 0x0A9E 2250xBD = 0x0A9F 2260xBE = 0x0AA0 2270xBF = 0x0AA1 2280xC0 = 0x0AA2 2290xC1 = 0x0AA3 2300xC2 = 0x0AA4 2310xC3 = 0x0AA5 2320xC4 = 0x0AA6 2330xC5 = 0x0AA7 2340xC6 = 0x0AA8 2350xC8 = 0x0AAA 2360xC9 = 0x0AAB 2370xCA = 0x0AAC 2380xCB = 0x0AAD 2390xCC = 0x0AAE 2400xCD = 0x0AAF 2410xCF = 0x0AB0 2420xD1 = 0x0AB2 2430xD2 = 0x0AB3 2440xD4 = 0x0AB5 2450xD5 = 0x0AB6 2460xD6 = 0x0AB7 2470xD7 = 0x0AB8 2480xD8 = 0x0AB9 2490xD9 = 0x200E 2500xDA = 0x0ABE 2510xDB = 0x0ABF 2520xDC = 0x0AC0 2530xDD = 0x0AC1 2540xDE = 0x0AC2 2550xDF = 0x0AC3 256#0xDF+0xE9 = 0x0AC4 2570xE1 = 0x0AC7 2580xE2 = 0x0AC8 2590xE3 = 0x0AC5 2600xE5 = 0x0ACB 2610xE6 = 0x0ACC 2620xE7 = 0x0AC9 2630xE8 = 0x0ACD 264#0xE8+0xE8 = 0x0ACD+0x200C 265#0xE8+0xE9 = 0x0ACD+0x200D 2660xE9 = 0x0ABC 2670xEA = 0x0964 2680xF1 = 0x0AE6 2690xF2 = 0x0AE7 2700xF3 = 0x0AE8 2710xF4 = 0x0AE9 2720xF5 = 0x0AEA 2730xF6 = 0x0AEB 2740xF7 = 0x0AEC 2750xF8 = 0x0AED 2760xF9 = 0x0AEE 2770xFA = 0x0AEF 278END_MAP 279
