Text-wrapping (or line-folding) library for displaying a string on
 the terminal. This supports i18n (internationalization), i.e,
 automatic locale-encoding detection, multibyte encoding (such as
 UTF-8, EUC-JP, and so on), fullwidth characters (occupying two
 columns per one character, like CJK Ideogram), combining characters
 (occupying zero columns per one character, like Thai and diacritical
 marks), and languages which do not use whitespaces between words
 (like Chinese and Japanese).
