Text::CharWidth - phpMan

NAME
    Text::CharWidth - Get number of occupied columns of a string on terminal

SYNOPSIS
      use Text::CharWidth qw(mbwidth mbswidth mblen);
      mbwidth(string);
      mbswidth(string);
      mblen(string);

DESCRIPTION
    This module supplies features similar as wcwidth(3) and wcswidth(3) in C
    language.

    Characters have its own width on terminal depending on locale. For
    example, ASCII characters occupy one column per character, east Asian
    fullwidth characters (like Hiragana or Han Ideograph) occupy two columns
    per character, and combining characters (apperaring in ISO-8859-11 Thai,
    Unicode, and so on) occupy zero columns per character. mbwidth() gives
    the width of the first character of the given string and mbswidth()
    gives the width of the whole given string.

    The names of mbwidth and mbswidth came from "multibyte" versions of
    wcwidth and wcswidth which are "wide character" versions.

    *mblen(string)* returns number of bytes of the first character of the
    string. Please note that a character may consist of multiple bytes in
    multibyte encodings such as UTF-8, EUC-JP, EUC-KR, GB2312, or Big5.

    *mbwidth(string)* returns the width of the first character of the
    string. *mbswidth(string)* returns the width of the whole string.

    Parameters are to be given in locale encodings, not always in UTF-8.
