1 Last update: 2005-01-17, version 1.4 2 3 This file is maintained by H. Peter Anvin <unicode@lanana.org> as part 4 of the Linux Assigned Names And Numbers Authority (LANANA) project. 5 The current version can be found at: 6 7 http://www.lanana.org/docs/unicode/unicode.txt 8 9 ------------------------ 10 11 The Linux kernel code has been rewritten to use Unicode to map 12 characters to fonts. By downloading a single Unicode-to-font table, 13 both the eight-bit character sets and UTF-8 mode are changed to use 14 the font as indicated. 15 16 This changes the semantics of the eight-bit character tables subtly. 17 The four character tables are now: 18 19 Map symbol Map name Escape code (G0) 20 21 LAT1_MAP Latin-1 (ISO 8859-1) ESC ( B 22 GRAF_MAP DEC VT100 pseudographics ESC ( 0 23 IBMPC_MAP IBM code page 437 ESC ( U 24 USER_MAP User defined ESC ( K 25 26 In particular, ESC ( U is no longer "straight to font", since the font 27 might be completely different than the IBM character set. This 28 permits for example the use of block graphics even with a Latin-1 font 29 loaded. 30 31 Note that although these codes are similar to ISO 2022, neither the 32 codes nor their uses match ISO 2022; Linux has two 8-bit codes (G0 and 33 G1), whereas ISO 2022 has four 7-bit codes (G0-G3). 34 35 In accordance with the Unicode standard/ISO 10646 the range U+F000 to 36 U+F8FF has been reserved for OS-wide allocation (the Unicode Standard 37 refers to this as a "Corporate Zone", since this is inaccurate for 38 Linux we call it the "Linux Zone"). U+F000 was picked as the starting 39 point since it lets the direct-mapping area start on a large power of 40 two (in case 1024- or 2048-character fonts ever become necessary). 41 This leaves U+E000 to U+EFFF as End User Zone. 42 43 [v1.2]: The Unicodes range from U+F000 and up to U+F7FF have been 44 hard-coded to map directly to the loaded font, bypassing the 45 translation table. The user-defined map now defaults to U+F000 to 46 U+F0FF, emulating the previous behaviour. In practice, this range 47 might be shorter; for example, vgacon can only handle 256-character 48 (U+F000..U+F0FF) or 512-character (U+F000..U+F1FF) fonts. 49 50 51 Actual characters assigned in the Linux Zone 52 -------------------------------------------- 53 54 In addition, the following characters not present in Unicode 1.1.4 55 have been defined; these are used by the DEC VT graphics map. [v1.2] 56 THIS USE IS OBSOLETE AND SHOULD NO LONGER BE USED; PLEASE SEE BELOW. 57 58 U+F800 DEC VT GRAPHICS HORIZONTAL LINE SCAN 1 59 U+F801 DEC VT GRAPHICS HORIZONTAL LINE SCAN 3 60 U+F803 DEC VT GRAPHICS HORIZONTAL LINE SCAN 7 61 U+F804 DEC VT GRAPHICS HORIZONTAL LINE SCAN 9 62 63 The DEC VT220 uses a 6x10 character matrix, and these characters form 64 a smooth progression in the DEC VT graphics character set. I have 65 omitted the scan 5 line, since it is also used as a block-graphics 66 character, and hence has been coded as U+2500 FORMS LIGHT HORIZONTAL. 67 68 [v1.3]: These characters have been officially added to Unicode 3.2.0; 69 they are added at U+23BA, U+23BB, U+23BC, U+23BD. Linux now uses the 70 new values. 71 72 [v1.2]: The following characters have been added to represent common 73 keyboard symbols that are unlikely to ever be added to Unicode proper 74 since they are horribly vendor-specific. This, of course, is an 75 excellent example of horrible design. 76 77 U+F810 KEYBOARD SYMBOL FLYING FLAG 78 U+F811 KEYBOARD SYMBOL PULLDOWN MENU 79 U+F812 KEYBOARD SYMBOL OPEN APPLE 80 U+F813 KEYBOARD SYMBOL SOLID APPLE 81 82 Klingon language support 83 ------------------------ 84 85 In 1996, Linux was the first operating system in the world to add 86 support for the artificial language Klingon, created by Marc Okrand 87 for the "Star Trek" television series. This encoding was later 88 adopted by the ConScript Unicode Registry and proposed (but ultimately 89 rejected) for inclusion in Unicode Plane 1. Thus, it remains as a 90 Linux/CSUR private assignment in the Linux Zone. 91 92 This encoding has been endorsed by the Klingon Language Institute. 93 For more information, contact them at: 94 95 http://www.kli.org/ 96 97 Since the characters in the beginning of the Linux CZ have been more 98 of the dingbats/symbols/forms type and this is a language, I have 99 located it at the end, on a 16-cell boundary in keeping with standard 100 Unicode practice. 101 102 NOTE: This range is now officially managed by the ConScript Unicode 103 Registry. The normative reference is at: 104 105 http://www.evertype.com/standards/csur/klingon.html 106 107 Klingon has an alphabet of 26 characters, a positional numeric writing 108 system with 10 digits, and is written left-to-right, top-to-bottom. 109 110 Several glyph forms for the Klingon alphabet have been proposed. 111 However, since the set of symbols appear to be consistent throughout, 112 with only the actual shapes being different, in keeping with standard 113 Unicode practice these differences are considered font variants. 114 115 U+F8D0 KLINGON LETTER A 116 U+F8D1 KLINGON LETTER B 117 U+F8D2 KLINGON LETTER CH 118 U+F8D3 KLINGON LETTER D 119 U+F8D4 KLINGON LETTER E 120 U+F8D5 KLINGON LETTER GH 121 U+F8D6 KLINGON LETTER H 122 U+F8D7 KLINGON LETTER I 123 U+F8D8 KLINGON LETTER J 124 U+F8D9 KLINGON LETTER L 125 U+F8DA KLINGON LETTER M 126 U+F8DB KLINGON LETTER N 127 U+F8DC KLINGON LETTER NG 128 U+F8DD KLINGON LETTER O 129 U+F8DE KLINGON LETTER P 130 U+F8DF KLINGON LETTER Q 131 - Written <q> in standard Okrand Latin transliteration 132 U+F8E0 KLINGON LETTER QH 133 - Written <Q> in standard Okrand Latin transliteration 134 U+F8E1 KLINGON LETTER R 135 U+F8E2 KLINGON LETTER S 136 U+F8E3 KLINGON LETTER T 137 U+F8E4 KLINGON LETTER TLH 138 U+F8E5 KLINGON LETTER U 139 U+F8E6 KLINGON LETTER V 140 U+F8E7 KLINGON LETTER W 141 U+F8E8 KLINGON LETTER Y 142 U+F8E9 KLINGON LETTER GLOTTAL STOP 143 144 U+F8F0 KLINGON DIGIT ZERO 145 U+F8F1 KLINGON DIGIT ONE 146 U+F8F2 KLINGON DIGIT TWO 147 U+F8F3 KLINGON DIGIT THREE 148 U+F8F4 KLINGON DIGIT FOUR 149 U+F8F5 KLINGON DIGIT FIVE 150 U+F8F6 KLINGON DIGIT SIX 151 U+F8F7 KLINGON DIGIT SEVEN 152 U+F8F8 KLINGON DIGIT EIGHT 153 U+F8F9 KLINGON DIGIT NINE 154 155 U+F8FD KLINGON COMMA 156 U+F8FE KLINGON FULL STOP 157 U+F8FF KLINGON SYMBOL FOR EMPIRE 158 159 Other Fictional and Artificial Scripts 160 -------------------------------------- 161 162 Since the assignment of the Klingon Linux Unicode block, a registry of 163 fictional and artificial scripts has been established by John Cowan 164 <jcowan@reutershealth.com> and Michael Everson <everson@evertype.com>. 165 The ConScript Unicode Registry is accessible at: 166 167 http://www.evertype.com/standards/csur/ 168 169 The ranges used fall at the low end of the End User Zone and can hence 170 not be normatively assigned, but it is recommended that people who 171 wish to encode fictional scripts use these codes, in the interest of 172 interoperability. For Klingon, CSUR has adopted the Linux encoding. 173 The CSUR people are driving adding Tengwar and Cirth into Unicode 174 Plane 1; the addition of Klingon to Unicode Plane 1 has been rejected 175 and so the above encoding remains official.
