For the sake of brevity, # throughout this document, "Macintosh" can be used to refer to # Macintosh computers and "Unicode" can be used to refer to the # Unicode standard. # # Apple makes no warranty or representation, either express or # implied, with respect to these tables, their quality, accuracy, or # fitness for a particular purpose. In no event will Apple be liable # for direct, indirect, special, incidental, or consequential damages # resulting from any defect or inaccuracy in this document or the # accompanying tables. # # These mapping tables and character lists are subject to change. # The latest tables should be available from the following: # # <ftp://ftp.unicode.org/Public/MAPPINGS/VENDORS/APPLE/> # <ftp://dev.apple.com/devworld/Technical_Documentation/Misc._Standards/> # # For general information about Mac OS encodings and these mapping # tables, see the file "README.TXT". # # Format: # ------- # # Three tab-separated columns; # '#' begins a comment which continues to the end of the line. # Column #1 is the Mac OS Symbol code (in hex as 0xNN) # Column #2 is the corresponding Unicode or Unicode sequence # (in hex as 0xNNNN or 0xNNNN+0xNNNN). # Column #3 is a comment containing the Unicode name. # In some cases an additional comment follows the Unicode name. # # The entries are in Mac OS Symbol code order. # # Some of these mappings require the use of corporate characters. # See the file "CORPCHAR.TXT" and notes below. # # Control character mappings are not shown in this table, following # the conventions of the standard UTC mapping tables. However, the # Mac OS Symbol character set uses the standard control characters # at 0x00-0x1F and 0x7F. # # Notes on Mac OS Symbol: # ----------------------- # # The Mac OS Symbol encoding shares the script code smRoman # (0) with the Mac OS Roman encoding. To determine if the Symbol # encoding is being used, you must check if the font name is # "Symbol". # # Before Mac OS 8.5, code point 0xA0 was unused. In Mac OS 8.5 # and later versions, code point 0xA0 is EURO SIGN and maps to # U+20AC (the Symbol font is updated for Mac OS 8.5 to reflect # this). Note: U+20AC is new with Unicode 2.1; for earlier Unicode # versions, Mac OS Symbol 0xA0 may be mapped to private-use # character U+F8A0. # # The layout of the Mac OS Symbol character set is identical to # the layout of the Adobe Symbol encoding vector, with the # addition of the Apple logo character at 0xF0. # # This character set encodes a number of glyph fragments. Some are # used as extenders: 0x60 is used to extend radical signs, 0xBD and # 0xBE are used to extend vertical and horizontal arrows, etc. In # addition, there are top, bottom, and center sections for # parentheses, brackets, integral signs, and other signs that may # extend vertically for 2 or more lines of normal text. In general, # Unicode does not encode such fragments, so these are mapping # using corporate-zone Unicode characters (see below). # # In addition, Symbol separately encodes both serif and sans-serif # forms for copyright, trademark, and registered signs. Unicode # encodes only the abstract characters, so one set of these (the # sans-serif forms) are also mapped using corporate-zone Unicode # characters (see below). # # The following code points are unused, and are not shown here: # 0x80-0x9F, 0xFF. # # Unicode mapping issues and notes: # --------------------------------- # # The goals in the mappings provided here are: # - Ensure roundtrip mapping from every character in the Mac OS # Symbol character set to Unicode and back # - Use standard Unicode characters as much as possible, to # maximize interchangeability of the resulting Unicode text. # Whenever possible, avoid having content carried by private-use # characters. # # Some of the characters in the Mac OS Symbol character set do not # correspond to distinct, single Unicode characters. To map these # and satisfy both goals above, we employ various strategies. # # a) If possible, use private use characters in combination with # standard Unicode characters to mark variants of the standard # Unicode character. # # 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 hints used in this mapping table are four # variant tags, 0xF870-72 and 0xF87F. Since these are combined with # standard Unicode characters, some characters in the Mac OS Symbol # character set map to a sequence of two Unicodes instead of a single # Unicode character. # # For example, the Mac OS Symbol character at 0xE2 is an alternate, # sans-serif form of the REGISTERED SIGN (the standard mapping is for # the abstract character at 0xD2, which here has a serif form). So 0xE2 # is mapped to 0x00AE (REGISTERED SIGN) + 0xF87F (a variant tag). # # b) Otherwise, use private use characters by themselves to map # Mac OS Symbol characters which have no relationship to any standard # Unicode character. # # The following additional corporate zone Unicode characters are # used for this purpose here: # # 0xF8E5 radical extender # 0xF8E6 vertical arrow extender # 0xF8E7 horizontal arrow extender # 0xF8F4 curly bracket extender # 0xF8FF Apple logo # # NOTE: The graphic image associated with the Apple logo character # is not authorized for use without permission of Apple, and # unauthorized use might constitute trademark infringement. # # Details of mapping changes in each version: # ------------------------------------------- # # Changes from version n05 to version b02: # # - Encoding changed for Mac OS 8.5; 0xA0 now maps to 0x20AC, EURO # SIGN. 0xA0 was unmapped in earlier versions. # # Changes from version n03 to version n05: # # - Change strict mapping for 0xE1 & 0xF1 from U+2329 & U+232A # to their canonical decompositions, U+3008 & U+3009. # # - Change mapping for the following to use standard Unicode + # transcoding hint, instead of single corporate-zone # character: 0xE2-0xE4, 0xE6-0xEE, 0xF4, 0xF6-0xFE. # ################## 0x20 0x0020 # SPACE 0x21 0x0021 # EXCLAMATION MARK 0x22 0x2200 # FOR ALL 0x23 0x0023 # NUMBER SIGN 0x24 0x2203 # THERE EXISTS 0x25 0x0025 # PERCENT SIGN 0x26 0x0026 # AMPERSAND 0x27 0x220D # SMALL CONTAINS AS MEMBER 0x28 0x0028 # LEFT PARENTHESIS 0x29 0x0029 # RIGHT PARENTHESIS 0x2A 0x2217 # ASTERISK OPERATOR 0x2B 0x002B # PLUS SIGN 0x2C 0x002C # COMMA 0x2D 0x2212 # MINUS SIGN 0x2E 0x002E # FULL STOP 0x2F 0x002F # SOLIDUS 0x30 0x0030 # DIGIT ZERO 0x31 0x0031 # DIGIT ONE 0x32 0x0032 # DIGIT TWO 0x33 0x0033 # DIGIT THREE 0x34 0x0034 # DIGIT FOUR 0x35 0x0035 # DIGIT FIVE 0x36 0x0036 # DIGIT SIX 0x37 0x0037 # DIGIT SEVEN 0x38 0x0038 # DIGIT EIGHT 0x39 0x0039 # DIGIT NINE 0x3A 0x003A # COLON 0x3B 0x003B # SEMICOLON 0x3C 0x003C # LESS-THAN SIGN 0x3D 0x003D # EQUALS SIGN 0x3E 0x003E # GREATER-THAN SIGN 0x3F 0x003F # QUESTION MARK 0x40 0x2245 # APPROXIMATELY EQUAL TO 0x41 0x0391 # GREEK CAPITAL LETTER ALPHA 0x42 0x0392 # GREEK CAPITAL LETT...
