However, the +# Mac OS Arabic character set uses the standard control characters at +# 0x00-0x1F and 0x7F. +# +# Notes on Mac OS Arabic: +# ----------------------- +# +# 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. +# +# 1. General +# +# The Mac OS Arabic character set is intended to cover Arabic as +# used in North Africa, the Arabian peninsula, and the Levant. It +# also contains several characters needed for Urdu and/or Farsi. +# +# The Mac OS Arabic character set is essentially a superset of ISO +# 8859-6. The 8859-6 code points that are interpreted differently +# in the Mac OS Arabic set are as follows: +# 0xA0 is NO-BREAK SPACE in 8859-6 and right-left SPACE in Mac OS +# Arabic; NO-BREAK is 0x81 in Mac OS Arabic. +# 0xA4 is CURRENCY SIGN in 8859-6 and right-left DOLLAR SIGN in +# Mac OS Arabic. +# 0xAD is SOFT HYPHEN in 8859-6 and right-left HYPHEN-MINUS in +# Mac OS Arabic. +# ISO 8859-6 specifies that codes 0x30-0x39 can be rendered either +# with European digit shapes or Arabic digit shapes. This is also +# true in Mac OS Arabic, which determines from context which digit +# shapes to use (see below). +# +# The Mac OS Arabic character set uses the C1 controls area and other +# code points which are undefined in ISO 8859-6 for additional +# graphic characters: additional Arabic letters for Farsi and Urdu, +# some accented Roman letters for European languages (such as French), +# and duplicates of some of the punctuation, symbols, and digits in +# the ASCII block. The duplicate punctuation, symbol, and digit +# characters have right-left directionality, while the ASCII versions +# have left-right directionality. See the next section for more +# information on this. +# +# Mac OS Arabic characters 0xEB-0xF2 are non-spacing/combining marks. +# +# 2. Directional characters and roundtrip fidelity +# +# The Mac OS Arabic character set was developed in 1986-1987. At that +# time the bidirectional line layout algorithm used in the Mac OS +# Arabic system was fairly simple; it used only a few direction +# classes (instead of the 19 now used in the Unicode bidirectional +# algorithm). In order to permit users to handle some tricky layout +# problems, certain punctuation and symbol characters were encoded +# twice, one with a left-right direction attribute and the other with +# a right-left direction attribute. +# +# For example, plus sign is encoded at 0x2B with a left-right +# attribute, and at 0xAB with a right-left attribute. However, there +# is only one PLUS SIGN character in Unicode. This leads to some +# interesting problems when mapping between Mac OS Arabic and Unicode; +# see below. +# +# A related problem is that even when a particular character is +# encoded only once in Mac OS Arabic, it may have a different +# direction attribute than the corresponding Unicode character. +# +# For example, the Mac OS Arabic character at 0x93 is HORIZONTAL +# ELLIPSIS with strong right-left direction. However, the Unicode +# character HORIZONTAL ELLIPSIS has direction class neutral. +# +# 3. Behavior of ASCII-range numbers in WorldScript +# +# Mac OS Arabic also has two sets of digit codes. +# +# The digits at 0x30-0x39 may be displayed using either European +# digit forms or Arabic digit forms, depending on context. If there +# is a "strong European" character such as a Latin letter on either +# side of a sequence consisting of digits 0x30-0x39 and possibly comma +# 0x2C or period 0x2E, then the characters will be displayed using +# European forms (This will happen even if there are neutral characters +# between the digits and the strong European character). Otherwise, the +# digits will be displayed using Arabic forms, the comma will be +# displayed as Arabic thousands separator, and the period as Arabic +# decimal separator. In any case, 0x2C, 0x2E, and 0x30-0x39 are always +# left-right. +# +# The digits at 0xB0-0xB9 are always displayed using Arabic digit +# shapes, and moreover, these digits always have strong right-left +# directionality. These are mainly intended for special layout +# purposes such as part numbers, etc. +# +# 4. Font variants +# +# The table in this file gives the Unicode mappings for the standard +# Mac OS Arabic encoding. This encoding is supported by the Cairo font +# (the system font for Arabic), and is the encoding supported by the +# text processing utilities. However, the other Arabic fonts actually +# implement slightly different encodings; this mainly affects the code +# points 0xAA and 0xC0. For these code points the standard Mac OS +# Arabic encoding has the following mappings: +# 0xAA -> <RL>+0x002A ASTERISK, right-left +# 0xC0 -> <RL>+0x274A EIGHT TEARDROP-SPOKED PROPELLER ASTERISK, +# right-left +# This mapping of 0xAA is consistent with the normal convention for +# Mac OS Arabic and Hebrew that the right-left duplicates have codes +# that are equal to the ASCII code of the left-right character plus +# 0x80. However, in all of the other fonts, 0xAA is MULTIPLY SIGN, and +# right-left ASTERISK may be at a different code point. The other +# variants are described below. +# +# The TrueType variant is used for most of the Arabic TrueType fonts: +# Baghdad, Geeza, Kufi, Nadeem. It differs from the standard variant +# in the following way: +# 0xAA -> <RL>+0x00D7 MULTIPLICATION SIGN, right-left +# 0xC0 -> <RL>+0x002A ASTERISK, right-left +# +# The Thuluth variant is used for the Arabic Postscript-only fonts: +# Thuluth and Thuluth bold. It differs from the standard variant in +# the following way: +# 0xAA -> <RL>+0x00D7 MULTIPLICATION SIGN, right-left +# 0xC0 -> 0x066D ARABIC FIVE POINTED STAR +# +# The AlBayan variant is used for the Arabic TrueType font Al Bayan. +# It differs from the standard variant in the following way: +# 0x81 -> no mapping (glyph just has authorship information, etc.) +# 0xA3 -> 0xFDFA ARABIC LIGATURE SALLALLAHOU ALAYHE WASALLAM +# 0xA4 -> 0xFDF2 ARABIC LIGATURE ALLAH ISOLATED FORM +# 0xAA -> <RL>+0x00D7 MULTIPLICATION SIGN, right-left +# 0xDC -> <RL>+0x25CF BLACK CIRCLE, right-left +# 0xFC -> <RL>+0x25A0 BLACK SQUARE, right-left +# +# Unicode mapping issues and notes: +# --------------------------------- +# +# 1. Matching the direction of Mac OS Arabic characters +# +# When Mac OS Arabic encodes a character twice but with different +# direction attributes for the two code points - as in the case of +# plus sign mentioned above - we need a way to map both Mac OS Arabic +# code points to Unicode and back again without loss of information. +# With the plus sign, for example, mapping one of the Mac OS Arabic +# characters to a code in the Unicode corporate use zone is +# undesirable, since both of the plus sign characters are likely to +# be used in text that is interchanged. +# +# The problem is solved with the use of direction override characters +# and direction-dependent mappings. When mapping from Mac OS Arabic +# to Unicode, we use direction overrides as necessary to force the +# direction of the resulting Unicode characters. +# +# The required direction is indicated by a direction tag in the +# mappings. A tag of <LR> means the corresponding Unicode character +# must have a strong left-right context, and a tag of <RL> indicates +# a right-left context. +# +# For example, the mapping of 0x2B is given as <LR>+0x002B; the +# mapping of 0xAB is given as <RL>+0x002B. If we map an isolated +# instance of 0x2B to Unicode, it should be mapped as follows (LRO +# indicates LEFT-RIGHT OVERRIDE, PDF indicates POP DIRECTION +# FORMATTING): +# +# 0x2B -> 0x202D (LRO) + 0x002B (PLUS SIGN) + 0x202C (PDF) +# +# When mapping several characters in a row that require direction +# forcing, the overrides need only be used at the beginning and end. +# For example: +# +# 0x24 0x20 0x28 0x29 -> 0x202D 0x0024 0x0020 0x0028 0x0029 0x202C +# +# If neutral characters that require direction forcing are already +# between strong-direction characters with matching directionality, +# then direction overrides need not be used. Direction overrides are +# always needed to map the right-left digits at 0xB0-0xB9. +# +# When mapping from Unicode to Mac OS Arabic, the Unicode +# bidirectional algorithm should be used to determine resolved +# direction of the Unicode characters. The mapping from Unicode to +# Mac OS Arabic can then be disambiguated by the use of the resolved +# direction: +# +# Unicode 0x002B -> Mac OS Arabic 0x2B (if L) or 0xAB (if R) +# +# However, this also means the direction override characters should +# be discarded when mapping from Unicode to Mac OS Arabic (after +# they have been used to determine resolved direction), since the +# direction override information is carried by the code point itself. +# +# Even when direction overrides are not needed for roundtrip +# fidelity, they are sometimes used when mapping Mac OS Arabic +# characters to Unicode in order to achieve similar text layout with +# the resulting Unicode text. For example, the single Mac OS Arabic +# ellipsis character has direction class right-left,and there is no +# left-right version. However, the Unicode HORIZONTAL ELLIPSIS +# character has direction class neutral (which means it may end up +# with a resolved direction of left-right if surrounded by left-right +# characters). When mapping the Mac OS Arabic ellipsis to Unicode, it +# is surrounded with a direction override to help preserve proper +# text layout. The resolved direction is not needed or used when +# mapping the Unicode HORIZONTAL ELLIPSIS back to Mac OS Arabic. +# +# 2. Mapping the Mac OS Arabic digits +# +# The main table below contains mappings that should be used when +# strict round-trip fidelity is required. However, for numeric +# values, the mappings in that table will produce Unicode characters +# that may appear different than the Mac OS Arabic text displayed on +# a Mac OS system using WorldScript. This is because WorldScript +# uses context-dependent display for the 0x30-0x39 digits. +# +# If roundtrip fidelity is not required, then the following +# alternate mappings should be used when a sequence of 0x30-0x39 +# digits - possibly including 0x2C and 0x2E - occurs in an Arabic +# context (that is, when the first "strong" character on either side +# of the digit sequence is Arabic, or there is no strong character): +# +# 0x2C 0x066C # ARABIC THOUSANDS SEPARATOR +# 0x2E 0x066B # ARABIC DECIMAL SEPARATOR +# 0x30 0x0660 # ARABIC-INDIC DIGIT ZERO +# 0x31 0x0661 # ARABIC-INDIC DIGIT ONE +# 0x32 0x0662 # ARABIC-INDIC DIGIT TWO +# 0x33 0x0663 # ARABIC-INDIC DIGIT THREE +# 0x34 0x0664 # ARABIC-INDIC DIGIT FOUR +# 0x35 0x0665 # ARABIC-INDIC DIGIT FIVE +# 0x36 0x0666 # ARABIC-INDIC DIGIT SIX +# 0x37 0x0667 # ARABIC-INDIC DIGIT SEVEN +# 0x38 0x0668 # ARABIC-INDIC DIGIT EIGHT +# 0x39 0x0669 # ARABIC-INDIC DIGIT NINE +# +# Details of mapping changes in each version: +# ------------------------------------------- +# +# Changes from version n03 to version n07: +# +# - Change mapping for 0xC0 from U+066D to U+274A. +# +# - Add direction overrides (required directionality) to mappings +# for 0x25, 0x2C, 0x3B, 0x3F. +# +################## +0x0000 - 0x007F = 0x00 - +0x00A0 = 0x81 +0x00AB = 0x8C +0x00BB = 0x98 +0x00C4 = 0x80 +0x00C7 = 0x82 +0x00C9 = 0x83 +0x00D1 = 0x84 +0x00D6 = 0x85 +0x00DC = 0x86 +0x00E0 = 0x88 +0x00E1 = 0x87 +0x00E2 = 0x89 +0x00E4 = 0x8A +0x00E7 = 0x8D +0x00E8 = 0x8F +0x00E9 = 0x8E +0x00EA = 0x90 +0x00EB = 0x91 +0x00ED = 0x92 +0x00EE = 0x94 +0x00EF = 0x95 +0x00F1 = 0x96 +0x00F3 = 0x97 +0x00F4 = 0x99 +0x00F6 = 0x9A +0x00F7 = 0x9B +0x00F9 = 0x9D +0x00FA = 0x9C +0x00FB = 0x9E +0x00FC = 0x9F +0x060C = 0xAC +0x061B = 0xBB +0x061F = 0xBF +0x0621 = 0xC1 +0x0622 = 0xC2 +0x0623 = 0xC3 +0x0624 = 0xC4 +0x0625 = 0xC5 +0x0626 = 0xC6 +0x0627 = 0xC7 +0x0628 = 0xC8 +0x0629 = 0xC9 +0x062A = 0xCA +0x062B = 0xCB +0x062C = 0xCC +0x062D = 0xCD +0x062E = 0xCE +0x062F = 0xCF +0x0630 = 0xD0 +0x0631 = 0xD1 +0x0632 = 0xD2 +0x0633 = 0xD3 +0x0634 = 0xD4 +0x0635 = 0xD5 +0x0636 = 0xD6 +0x0637 = 0xD7 +0x0638 = 0xD8 +0x0639 = 0xD9 +0x063A = 0xDA +0x0640 = 0xE0 +0x0641 = 0xE1 +0x0642 = 0xE2 +0x0643 = 0xE3 +0x0644 = 0xE4 +0x0645 = 0xE5 +0x0646 = 0xE6 +0x0647 = 0xE7 +0x0648 = 0xE8 +0x0649 = 0xE9 +0x064A = 0xEA +0x064B = 0xEB +0x064C = 0xEC +0x064D = 0xED +0x064E = 0xEE +0x064F = 0xEF +0x0650 = 0xF0 +0x0651 = 0xF1 +0x0652 = 0xF2 +0x0660 = 0xB0 +0x0661 = 0xB1 +0x0662 = 0xB2 +0x0663 = 0xB3 +0x0664 = 0xB4 +0x0665 = 0xB5 +0x0666 = 0xB6 +0x0667 = 0xB7 +0x0668 = 0xB8 +0x0669 = 0xB9 +0x066A = 0xA5 +0x066D = 0xC0 +0x0679 = 0xF4 +0x067E = 0xF3 +0x0686 = 0xF5 +0x0688 = 0xF9 +0x0691 = 0xFA +0x0698 = 0xFE +0x06A4 = 0xF7 +0x06AF = 0xF8 +0x06BA = 0x8B +0x06D2 = 0xFF +0x06D5 = 0xF6 +0x2026 = 0x93 +0x274A = 0xC0 +END_MAP |
