#
# 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.
