The Unicode data is 39 * transformed into tables in this file by a script "uniset" written by Kuhn. 40 * 41 * While Kuhn implemented the original CJK variant, it was unused by xterm 42 * until Jungshik Shin used it in 2002 to implement the -cjk_width command-line 43 * option. 44 * 45 * Kuhn added a check for the vertical forms block (double-width) in 2007; 46 * other updates were derived from the Unicode.org data (release 5.0). 47 * 48 * Since then, additional updates have been made: 49 * + data-type fixes 50 * + new Unicode releases (6.2.0, 9.0.0, etc), 51 * + additional special symbol blocks have been added to the special cases. 52 * + soft-hyphen behavior has been made configurable. 53 * + added table shows when a character is not part of Unicode. 54 * 55 * Kuhn's original header follows giving the design information: 56 *----------------------------------------------------------------------------- 57 * This is an implementation of wcwidth() and wcswidth() (defined in 58 * IEEE Std 1002.1-2001) for Unicode. 59 * 60 * http://www.opengroup.org/onlinepubs/007904975/functions/wcwidth.html 61 * http://www.opengroup.org/onlinepubs/007904975/functions/wcswidth.html 62 * 63 * In fixed-width output devices, Latin characters all occupy a single 64 * "cell" position of equal width, whereas ideographic CJK characters 65 * occupy two such cells. Interoperability between terminal-line 66 * applications and (teletype-style) character terminals using the 67 * UTF-8 encoding requires agreement on which character should advance 68 * the cursor by how many cell positions. No established formal 69 * standards exist at present on which Unicode character shall occupy 70 * how many cell positions on character terminals. These routines are 71 * a first attempt of defining such behavior based on simple rules 72 * applied to data provided by the Unicode Consortium. 73 * 74 * For some graphical characters, the Unicode standard explicitly 75 * defines a character-cell width via the definition of the East Asian 76 * FullWidth (F), Wide (W), Half-width (H), and Narrow (Na) classes. 77 * In all these cases, there is no ambiguity about which width a 78 * terminal shall use. For characters in the East Asian Ambiguous (A) 79 * class, the width choice depends purely on a preference of backward 80 * compatibility with either historic CJK or Western practice. 81 * Choosing single-width for these characters is easy to justify as 82 * the appropriate long-term solution, as the CJK practice of 83 * displaying these characters as double-width comes from historic 84 * implementation simplicity (8-bit encoded characters were displayed 85 * single-width and 16-bit ones double-width, even for Greek, 86 * Cyrillic, etc.) and not any typographic considerations. 87 * 88 * Much less clear is the choice of width for the Not East Asian 89 * (Neutral) class. Existing practice does not dictate a width for any 90 * of these characters. It would nevertheless make sense 91 * typographically to allocate two character cells to characters such 92 * as for instance EM SPACE or VOLUME INTEGRAL, which cannot be 93 * represented adequately with a single-width glyph. The following 94 * routines at present merely assign a single-cell width to all 95 * neutral characters, in the interest of simplicity. This is not 96 * entirely satisfactory and should be reconsidered before 97 * establishing a formal standard in this area. At the moment, the 98 * decision which Not East Asian (Neutral) characters should be 99 * represented by double-width glyphs cannot yet be answered by 100 * applying a simple rule from the Unicode database content. Setting 101 * up a proper standard for the behavior of UTF-8 character terminals 102 * will require a careful analysis not only of each Unicode character, 103 * but also of each presentation form, something the author of these 104 * routines has avoided to do so far. 105 * 106 * http://www.unicode.org/unicode/reports/tr11/ 107 * 108 * Markus Kuhn -- 2007-05-25 (Unicode 5.0) 109 * 110 * Permission to use, copy, modify, and distribute this software 111 * for any purpose and without fee is hereby granted.
