- Text::CharWidth version 0.04
- ============================
-
- This is a module to provide equivalent feature as wcwidth(3) and
- wcswidth(3). This also provides mblen(3) equivalent subroutine.
-
- mbwidth() and mbswidth() are provided subroutines corresponding
- wcwidth(3) and wcswidth(3) in C language. The prefix "mb" expresses
- that they handles "multibyte character" in C meaning, i.e., character
- encoding specified by LC_CTYPE locale.
-
- These subroutines are used to get the width of characters on terminal.
- Though most characters have width of 1, there are exceptions.
- Fullwidth characters are characters with width of 2. Most of east
- Asian characters such as Hiragana, Katakana, Hangul, Han Ideogram
- are fullwidth. Combining characters are characters with width of 0.
- Unicode has many combining characters like diacritical marks. There
- are languages which need combining characters such as Thai and
- Vietnamese.
-
- Thus, if you would like to format international texts on terminal,
- you will have to be aware of variation of character width and will
- want to use this module.
-
- mblen() returns the number of bytes for the first character of
- the given string. In 8bit character encodings, it is always 1.
- However, in multibyte encodings, this may be more than 1.
-
- The parameter is given in locale encoding, not UTF-8 string.
- (Of course locale encoding is UTF-8 in UTF-8 locales.)
-
-
- Prerequisites
- -------------
-
- This module requires your system to have wcwidth(), wcswidth(), and
- mblen() functions which are complian with the Single Unix Specification.
