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 Gurmukhi 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 Gurmukhi code order. +# +# Control character mappings are not shown in this table, following +# the conventions of the standard UTC mapping tables. However, the +# Mac OS Gurmukhi character set uses the standard control characters +# at 0x00-0x1F and 0x7F. +# +# Notes on Mac OS Gurmukhi: +# ------------------------- +# +# 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 Gurmukhi is based on IS 13194:1991 (ISCII-91), with the +# addition of several punctuation and symbol characters. However, +# Mac OS Gurmukhi does not support the ATR (attribute) mechanism of +# ISCII-91. +# +# 1. ISCII-91 features in Mac OS Gurmukhi include: +# +# a) 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. +# +# b) 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. +# +# c) 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 Gurmukhi supports this mechanism, but +# does not currently map any of these two-byte code points to +# anything. +# +# 2. Mac OS Gurmukhi additions +# +# Mac OS Gurmukhi adds characters using the code points +# 0x80-0x8A and 0x90-0x94 (the latter are some Gurmukhi additions). +# +# 3. Unused code points +# +# The following code points are currently unused, and are not shown +# here: 0x8B-0x8F, 0x95-0xA1, 0xA3, 0xAA-0xAB, 0xAE-0xAF, 0xB2, +# 0xC7, 0xCE, 0xD0, 0xD2-0xD3, 0xD6, 0xDF-0xE0, 0xE3-0xE4, 0xE7, +# 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 the byte value 0xE8 is encountered when mapping Mac OS +# Gurmukhi text, then the next byte (if there is one) should be +# examined. If the next byte is 0xE8 or 0xE9, 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 +# Gurmukhi 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. Mappings using corporate characters +# +# Mapping the GURMUKHI LETTER SHA 0xD5 presents an interesting +# problem. At first glance, we could map it to the single Unicode +# character 0x0A36. +# +# However, our goal is that the mappings provided here should also +# be able to generate the mappings to maximally decomposed Unicode +# by simple recursive substitution of the canonical decompositions +# in the Unicode database. We want mapping tables derived this way +# to retain full roundtrip fidelity. +# +# Since the canonical decomposition of 0x0A36 is 0x0A38+0x0A3C, +# the decomposition mapping for 0xD5 would be identical with the +# decomposition mapping for 0xD7+0xE9, and roundtrip fidelity would +# be lost. +# +# We solve this problem by using a grouping hint (one of the set of +# transcoding hints defined by Apple). +# +# 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 hint used in this mapping table is: +# 0xF860 group next 2 characters +# +# Then we can map 0x91 as follows: +# 0xD5 -> 0xF860+0x0A38+0x0A3C +# +# We could also have used a variant tag such as 0xF87F and mapped it +# this way: +# 0xD5 -> 0x0A36+0xF87F +# +# 4. Additional loose mappings from Unicode +# +# These are not preserved in roundtrip mappings. +# +# 0A59 -> 0xB4+0xE9 # GURMUKHI LETTER KHHA +# 0A5A -> 0xB5+0xE9 # GURMUKHI LETTER GHHA +# 0A5B -> 0xBA+0xE9 # GURMUKHI LETTER ZA +# 0A5E -> 0xC9+0xE9 # GURMUKHI LETTER FA +# +# 0A70 -> 0xA2 # GURMUKHI TIPPI +# +# Loose mappings from Unicode should also map U+0A71 (GURMUKHI ADDAK) +# followed by any Gurmukhi consonant to the equivalent ISCII-91 +# consonant plus halant plus the consonant again. For example: +# +# 0A71+0A15 -> 0xB3+0xE8+0xB3 +# 0A71+0A16 -> 0xB4+0xE8+0xB4 +# ... +# +# Details of mapping changes in each version: +# ------------------------------------------- +# +# Changes from version b02 to version b03/c01: +# +# - Change mapping of 0x91 from 0xF860+0x0A21+0x0A3C to 0x0A5C GURMUKHI +# LETTER RRA, now that the canonical decomposition of 0x0A5C to +# 0x0A21+0x0A3C has been deleted +# +# - Change mapping of 0xD5 from 0x0A36 GURMUKHI LETTER SHA to +# 0xF860+0x0A38+0x0A3C, now that a canonical decomposition of 0x0A36 +# to 0x0A38+0x0A3C has been added. +# +################## +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 = 0x0A71 +0x91 = 0x0A5C +0x92 = 0x0A73 +0x93 = 0x0A72 +0x94 = 0x0A74 +0xA2 = 0x0A02 +0xA4 = 0x0A05 +0xA5 = 0x0A06 +0xA6 = 0x0A07 +0xA7 = 0x0A08 +0xA8 = 0x0A09 +0xA9 = 0x0A0A +0xAC = 0x0A0F +0xAD = 0x0A10 +0xB0 = 0x0A13 +0xB1 = 0x0A14 +0xB3 = 0x0A15 +0xB4 = 0x0A16 +0xB5 = 0x0A17 +0xB6 = 0x0A18 +0xB7 = 0x0A19 +0xB8 = 0x0A1A +0xB9 = 0x0A1B +0xBA = 0x0A1C +0xBB = 0x0A1D +0xBC = 0x0A1E +0xBD = 0x0A1F +0xBE = 0x0A20 +0xBF = 0x0A21 +0xC0 = 0x0A22 +0xC1 = 0x0A23 +0xC2 = 0x0A24 +0xC3 = 0x0A25 +0xC4 = 0x0A26 +0xC5 = 0x0A27 +0xC6 = 0x0A28 +0xC8 = 0x0A2A +0xC9 = 0x0A2B +0xCA = 0x0A2C +0xCB = 0x0A2D +0xCC = 0x0A2E +0xCD = 0x0A2F +0xCF = 0x0A30 +0xD1 = 0x0A32 +0xD4 = 0x0A35 +#0xD5 = 0xF860+0x0A38+0x0A3C +0xD7 = 0x0A38 +0xD8 = 0x0A39 +0xD9 = 0x200E +0xDA = 0x0A3E +0xDB = 0x0A3F +0xDC = 0x0A40 +0xDD = 0x0A41 +0xDE = 0x0A42 +0xE1 = 0x0A47 +0xE2 = 0x0A48 +0xE5 = 0x0A4B +0xE6 = 0x0A4C +0xE8 = 0x0A4D +#0xE8+0xE8 = 0x0A4D+0x200C +#0xE8+0xE9 = 0x0A4D+0x200D +0xE9 = 0x0A3C +0xEA = 0x0964 +0xF1 = 0x0A66 +0xF2 = 0x0A67 +0xF3 = 0x0A68 +0xF4 = 0x0A69 +0xF5 = 0x0A6A +0xF6 = 0x0A6B +0xF7 = 0x0A6C +0xF8 = 0x0A6D +0xF9 = 0x0A6E +0xFA = 0x0A6F +END_MAP |
