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

NAME
Text::WrapI18N - Line wrapping module with support for multibyte, fullwidth, and combining characters and languages without whitespaces between words SYNOPSIS
use Text::WrapI18N qw(wrap $columns); wrap(firstheader, nextheader, texts); DESCRIPTION
This module intends to be a better Text::Wrap module. This module is needed to support multibyte character encodings such as UTF-8, EUC- JP, EUC-KR, GB2312, and Big5. This module also supports characters with irregular widths, such as combining characters (which occupy zero columns on terminal, like diacritical marks in UTF-8) and fullwidth characters (which occupy two columns on terminal, like most of east Asian characters). Also, minimal handling of languages which doesn't use whitespaces between words (like Chinese and Japanese) is supported. Like Text::Wrap, hyphenation and "kinsoku" processing are not supported, to keep simplicity. wrap(firstheader, nextheader, texts) is the main subroutine of Text::WrapI18N module to execute the line wrapping. Input parameters and output data emulate Text::Wrap. The texts have to be written in locale encoding. SEE ALSO
