 *-----------------------------------------------------------------------------
 * This is an updated version of Markus Kuhn's implementation of wcwidth.
 *
 * Originally added to xterm in 2000 (patch #141), there were a couple of
 * updates from Kuhn until 2005 (patch #202), renaming entrypoints and applying
 * data from Unicode.org (e.g., 3.2, 4.0, 4.1.0).  The Unicode data is
 * transformed into tables in this file by a script "uniset" written by Kuhn.
 *
 * While Kuhn implemented the original CJK variant, it was unused by xterm
 * until Jungshik Shin used it in 2002 to implement the -cjk_width command-line
 * option.
 *
 * Kuhn added a check for the vertical forms block (double-width) in 2007;
 * other updates were derived from the Unicode.org data (release 5.0).
 *
 * Since then, additional updates have been made:
 * + data-type fixes
 * + new Unicode releases (6.2.0, 9.0.0, etc),
 * + additional special symbol blocks have been added to the special cases.
 * + soft-hyphen behavior has been made configurable.
 * + added table shows when a character is not part of Unicode.
 *
 * Kuhn's original header follows giving the design information:
 *-----------------------------------------------------------------------------
 * This is an implementation of wcwidth() and wcswidth() (defined in
 * IEEE Std 1002.1-2001) for Unicode.
 *
 * http://www.opengroup.org/onlinepubs/007904975/functions/wcwidth.html
 * http://www.opengroup.org/onlinepubs/007904975/functions/wcswidth.html
 *
 * In fixed-width output devices, Latin characters all occupy a single
 * "cell" position of equal width, whereas ideographic CJK characters
 * occupy two such cells. Interoperability between terminal-line
 * applications and (teletype-style) character terminals using the
 * UTF-8 encoding requires agreement on which character should advance
 * the cursor by how many cell positions. No established formal
 * standards exist at present on which Unicode character shall occupy
 * how many cell positions on character terminals. These routines are
 * a first attempt of defining such behavior based on simple rules
 * applied to data provided by the Unicode Consortium.
 *
 * For some graphical characters, the Unicode standard explicitly
 * defines a character-cell width via the definition of the East Asian
 * FullWidth (F), Wide (W), Half-width (H), and Narrow (Na) classes.
 * In all these cases, there is no ambiguity about which width a
 * terminal shall use. For characters in the East Asian Ambiguous (A)
 * class, the width choice depends purely on a preference of backward
 * compatibility with either historic CJK or Western practice.
 * Choosing single-width for these characters is easy to justify as
 * the appropriate long-term solution, as the CJK practice of
 * displaying these characters as double-width comes from historic
 * implementation simplicity (8-bit encoded characters were displayed
 * single-width and 16-bit ones double-width, even for Greek,
 * Cyrillic, etc.) and not any typographic considerations.
 *
 * Much less clear is the choice of width for the Not East Asian
 * (Neutral) class. Existing practice does not dictate a width for any
 * of these characters. It would nevertheless make sense
 * typographically to allocate two character cells to characters such
 * as for instance EM SPACE or VOLUME INTEGRAL, which cannot be
 * represented adequately with a single-width glyph. The following
 * routines at present merely assign a single-cell width to all
 * neutral characters, in the interest of simplicity. This is not
 * entirely satisfactory and should be reconsidered before
 * establishing a formal standard in this area. At the moment, the
 * decision which Not East Asian (Neutral) characters should be
 * represented by double-width glyphs cannot yet be answered by
 * applying a simple rule from the Unicode database content. Setting
 * up a proper standard for the behavior of UTF-8 character terminals
 * will require a careful analysis not only of each Unicode character,
 * but also of each presentation form, something the author of these
 * routines has avoided to do so far.
