Linux 2.6 - man page for text::charwidth (linux section 3pm)

CharWidth(3pm)		       User Contributed Perl Documentation		   CharWidth(3pm)

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.

SEE ALSO
       locale(5), wcwidth(3), wcswidth(3)
