/*
|
||||||
|
* 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.
