48 # Three tab-separated columns;
49 # '#' begins a comment which continues to the end of the line.
50 # Column #1 is the Mac OS Gurmukhi code or code sequence
51 # (in hex as 0xNN or 0xNN+0xNN)
52 # Column #2 is the corresponding Unicode or Unicode sequence
53 # (in hex as 0xNNNN or 0xNNNN+0xNNNN).
54 # Column #3 is a comment containing the Unicode name or sequence
55 # of names. In some cases an additional comment follows the
56 # Unicode name(s).
57 #
58 # The entries are in two sections. The first section is for pairs of
59 # Mac OS Gurmukhi code points that must be mapped in a special way.
60 # The second section maps individual code points.
61 #
62 # Within each section, the entries are in Mac OS Gurmukhi code order.
63 #
64 # Control character mappings are not shown in this table, following
65 # the conventions of the standard UTC mapping tables. However, the
66 # Mac OS Gurmukhi character set uses the standard control characters
67 # at 0x00-0x1F and 0x7F.

69 # Notes on Mac OS Gurmukhi:
70 # -------------------------
71 #
72 # Mac OS Gurmukhi is based on IS 13194:1991 (ISCII-91), with the
73 # addition of several punctuation and symbol characters. However,
74 # Mac OS Gurmukhi does not support the ATR (attribute) mechanism of
75 # ISCII-91.
76 #
77 # 1. ISCII-91 features in Mac OS Gurmukhi include:
78 #
79 # a) Explicit halant and soft halant
80 #
81 # A double halant (0xE8 + 0xE8) constitutes an "explicit halant",
82 # which will always appear as a halant instead of causing formation
83 # of a ligature or half-form consonant.
84 #
85 # Halant followed by nukta (0xE8 + 0xE9) constitutes a "soft
86 # halant", which prevents formation of a ligature and instead
87 # retains the half-form of the first consonant.
88 #
89 # b) Invisible consonant
90 #
91 # The byte 0xD9 (called INV in ISCII-91) is an invisible consonant:
92 # It behaves like a consonant but has no visible appearance. It is
93 # intended to be used (often in combination with halant) to display
94 # dependent forms in isolation, such as the RA forms or consonant
95 # half-forms.
96 #
97 # c) Extensions for Vedic, etc.
98 #
99 # The byte 0xF0 (called EXT in ISCII-91) followed by any byte in
100 # the range 0xA1-0xEE constitutes a two-byte code point which can
101 # be used to represent additional characters for Vedic (or other
102 # extensions); 0xF0 followed by any other byte value constitutes
103 # malformed text. Mac OS Gurmukhi supports this mechanism, but
104 # does not currently map any of these two-byte code points to
105 # anything.
106 #
107 # 2. Mac OS Gurmukhi additions
108 #
109 # Mac OS Gurmukhi adds characters using the code points
110 # 0x80-0x8A and 0x90-0x94 (the latter are some Gurmukhi additions).
111 #
112 # The character at 0x91 is a special case. This is an alternate
113 # encoding for GURMUKHI LETTER RRA (corresponding to the single
114 # Unicode character 0x0A5C). The normal encoding in ISCII-91 and
115 # Mac OS Gurmukhi is 0xBF+0xE9 (corresponding to the Unicodes
116 # 0x0A21+0x0A3C, which are the canonical decomposition of 0x0A5C).
117 #
118 # 3. Unused code points
119 #
120 # The following code points are currently unused, and are not shown
121 # here: 0x8B-0x8F, 0x95-0xA1, 0xA3, 0xAA-0xAB, 0xAE-0xAF, 0xB2,
122 # 0xC7, 0xCE, 0xD0, 0xD2-0xD3, 0xD6, 0xDF-0xE0, 0xE3-0xE4, 0xE7,
123 # 0xEB-0xEF, 0xFB-0xFF. In addition, 0xF0 is not shown here, but it
124 # has a special function as described above.
125 #
126 # Unicode mapping issues and notes:
127 # ---------------------------------
128 #
129 # 1. Mapping the byte pairs
130 #
131 # If the byte value 0xE8 is encountered when mapping Mac OS
132 # Gurmukhi text, then the next byte (if there is one) should be
133 # examined. If the next byte is 0xE8 or 0xE9, then the byte pair
134 # should be mapped using the first section of the mapping table
135 # below. Otherwise, each byte should be mapped using the second
136 # section of the mapping table below.
137 #
138 # - The Unicode Standard, Version 2.0, specifies how explicit
139 # halant and soft halant should be represented in Unicode;
140 # these mappings are used below.
141 #
142 # If the byte value 0xF0 is encountered when mapping Mac OS
143 # Gurmukhi text, then the next byte should be examined. If there
144 # is no next byte (e.g. 0xF0 at end of buffer), the mapping
145 # process should indicate incomplete character. If there is a next
146 # byte but it is not in the range 0xA1-0xEE, the mapping process
147 # should indicate malformed text. Otherwise, the mapping process
148 # should treat the byte pair as a valid two-byte code point with no
149 # mapping (e.g. map it to QUESTION MARK, REPLACEMENT CHARACTER,
150 # etc.).
151 #
152 # 2. Mapping the invisible consonant
153 #
154 # It has been suggested that INV in ISCII-91 should map to ZERO
155 # WIDTH NON-JOINER in Unicode. However, this causes problems with
156 # roundtrip fidelity: The ISCII-91 sequences 0xE8+0xE8 and 0xE8+0xD9
157 # would map to the same sequence of Unicode characters. We have
158 # instead mapped INV to LEFT-TO-RIGHT MARK, which avoids these
159 # problems.
160 #
161 # 3. Mappings using corporate characters
162 #
163 # Mapping the GURMUKHI LETTER RRA alternate encoding 0x91 presents
164 # an interesting problem. At first glance, we could map it to the
165 # single Unicode character 0x0A5C, since we map the normal encoding
166 # of GURMUKHI LETTER RRA - 0xBF+0xE9 - to the Unicode sequence
167 # 0x0A21+0x0A3C.
168 #
169 # However, our goal is that the mappings provided here should also
170 # be able to generate the mappings to maximally decomposed Unicode
171 # by simple recursive substitution of the canonical decompositions
172 # in the Unicode database. We want mapping tables derived this way
173 # to retain full roundtrip fidelity.
174 #
175 # Since the canonical decomposition of 0x0A5C is 0x0A21+0x0A3C,
176 # the decomposition mapping for 0x91 would be identical with the
177 # decomposition mapping for 0xBF+0xE9, and roundtrip fidelity would
178 # be lost.
179 #
180 # We solve this problem by using a grouping hint (one of the set of
181 # transcoding hints defined by Apple).
182 #
183 # Apple has defined a block of 32 corporate characters as "transcoding
184 # hints." These are used in combination with standard Unicode characters
185 # to force them to be treated in a special way for mapping to other
186 # encodings; they have no other effect. Sixteen of these transcoding
187 # hints are "grouping hints" - they indicate that the next 2-4 Unicode
188 # characters should be treated as a single entity for transcoding. The
189 # other sixteen transcoding hints are "variant tags" - they are like
190 # combining characters, and can follow a standard Unicode (or a sequence
191 # consisting of a base character and other combining characters) to
192 # cause it to be treated in a special way for transcoding. These always
193 # terminate a combining-character sequence.
194 #
195 # The transcoding coding hint used in this mapping table is:
196 # 0xF860 group next 2 characters
197 #
198 # Then we can map 0x91 as follows:
199 # 0x91 -> 0xF860+0x0A21+0x0A3C
200 #
201 # We could also have used a variant tag such as 0xF87F and mapped it
202 # this way:
203 # 0x91 -> 0x0A5C+0xF87F
204 #
205 # 4. Additional loose mappings from Unicode
206 #
207 # These are not preserved in roundtrip mappings.
208 #
209 # 0A59 -> 0xB4+0xE9 # GURMUKHI LETTER KHHA
210 # 0A5A -> 0xB5+0xE9 # GURMUKHI LETTER GHHA
211 # 0A5B -> 0xBA+0xE9 # GURMUKHI LETTER ZA
212 # 0A5C -> 0xBF+0xE9 # GURMUKHI LETTER RRA
213 # 0A5E -> 0xC9+0xE9 # GURMUKHI LETTER FA
214 #
215 # 0A70 -> 0xA2 # GURMUKHI TIPPI
216 #
217 # Loose mappings from Unicode should also map U+0A71 (GURMUKHI ADDAK)
218 # followed by any Gurmukhi consonant to the equivalent ISCII-91
219 # consonant plus halant plus the consonant again. For example:
220 #
221 # 0A71+0A15 -> 0xB3+0xE8+0xB3
222 # 0A71+0A16 -> 0xB4+0xE8+0xB4
223 # ...
