However, the # Mac OS Farsi character set uses the standard control characters at # 0x00-0x1F and 0x7F. # # Notes on Mac OS Farsi: # ---------------------- # # 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 Farsi character set is based on the Mac OS Arabic # character set. The main difference is in the right-to-left digits # 0xB0-0xB9: For Mac OS Arabic these correspond to right-left # versions of the Unicode ARABIC-INDIC DIGITs 0660-0669; for # Mac OS Farsi these correspond to right-left versions of the # Unicode EXTENDED ARABIC-INDIC DIGITs 06F0-06F9. The other # difference is in the nature of the font variants. # # For more information, see the comments in the mapping table for # Mac OS Arabic. # # Mac OS Farsi characters 0xEB-0xF2 are non-spacing/combining marks. # # 2. Directional characters and roundtrip fidelity # # The Mac OS Arabic character set (on which Mac OS Farsi is based) # 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. This # is the case in Mac OS Farsi too. # # 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 Farsi and Unicode; # see below. # # A related problem is that even when a particular character is # encoded only once in Mac OS Farsi, it may have a different # direction attribute than the corresponding Unicode character. # # For example, the Mac OS Farsi 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 Farsi also has two sets of digit codes. # The digits at 0x30-0x39 may be displayed using either European # digit forms or Persian 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 Persian 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 Persian 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 Farsi encoding. This encoding is supported by the Tehran font # (the system font for Farsi), and is the encoding supported by the # text processing utilities. However, the other Farsi fonts actually # implement a somewhat different encoding; this affects nine code # points including 0xAA and 0xC0 (which are also affected by font # variants in Mac OS Arabic). For these nine code points the standard # Mac OS Farsi encoding has the following mappings: # 0x8B -> 0x06BA ARABIC LETTER NOON GHUNNA (Urdu) # 0xA4 -> +0x0024 DOLLAR SIGN, right-left # 0xAA -> +0x002A ASTERISK, right-left # 0xC0 -> +0x274A EIGHT TEARDROP-SPOKED PROPELLER ASTERISK, # right-left # 0xF4 -> 0x0679 ARABIC LETTER TTEH (Urdu) # 0xF7 -> 0x06A4 ARABIC LETTER VEH (for transliteration) # 0xF9 -> 0x0688 ARABIC LETTER DDAL (Urdu) # 0xFA -> 0x0691 ARABIC LETTER RREH (Urdu) # 0xFF -> 0x06D2 ARABIC LETTER YEH BARREE (Urdu) # # The TrueType variant is used for the Farsi TrueType fonts: Ashfahan, # Amir, Kamran, Mashad, NadeemFarsi. It differs from the standard # variant in the following ways: # 0x8B -> 0xF882 Arabic ligature "peace on him" (corporate char.) # 0xA4 -> 0xFDFC RIAL SIGN (added in Unicode 3.2) # 0xAA -> +0x00D7 MULTIPLICATION SIGN, right-left # 0xC0 -> +0x002A ASTERISK, right-left # 0xF4 -> +0x00B0 DEGREE SIGN, right-left # 0xF7 -> 0xFDFA ARABIC LIGATURE SALLALLAHOU ALAYHE WASALLAM # 0xF9 -> +0x25CF BLACK CIRCLE, right-left # 0xFA -> +0x25A0 BLACK SQUARE, right-left # 0xFF -> +0x25B2 BLACK UP-POINTING TRIANGLE, right-left # # Unicode mapping issues and notes: # --------------------------------- # # 1. Matching the direction of Mac OS Farsi characters # # When Mac OS Farsi 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 Farsi # code points to Unicode and back again without loss of information. # With the plus sign, for example, mapping one of the Mac OS Farsi # 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 Farsi # 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 means the corresponding Unicode character # must have a strong left-right context, and a tag of indicates # a right-left context. # # For example, the mapping of 0x2B is given as +0x002B; the # mapping of 0xAB is given as +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 Farsi, the Unicode # bidirectional algorithm should be used to determine resolved # direction of the Unicode characters. The mapping from Unicode to # Mac OS Farsi can then be disambiguated by the use of the resolved # direction: # # Unicode 0x002B -> Mac OS Farsi 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 Farsi (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 Farsi # characters to Unicode in order to achieve similar text layout with # the resulting Unicode text. For example, the single Mac OS Farsi # 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 Farsi 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 Farsi. # # 2. Mapping the Mac OS Farsi 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 Farsi 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 0x06F0 # EXTENDED ARABIC-INDIC DIGIT ZERO # 0x31 0x06F1 # EXTENDED ARABIC-INDIC DIGIT ONE # 0x32 0x06F2 # EXTENDED ARABIC-INDIC DIGIT TWO # 0x33 0x06F3 # EXTENDED ARABIC-INDIC DIGIT THREE # 0x34 0x06F4 # EXTENDED ARABIC-INDIC DIGIT FOUR # 0x35 0x06F5 # EXTENDED ARABIC-INDIC DIGIT FIVE # 0x36 0x06F6 # EXTENDED ARABIC-INDIC DIGIT SIX # 0x37 0x06F7 # EXTENDED ARABIC-INDIC DIGIT SEVEN # 0x38 0x06F8 # EXTENDED ARABIC-INDIC DIGIT EIGHT # 0x39 0x06F9 # EXTENDED ARABIC-INDIC DIGIT NINE # # 3.
