# Введение

This module contains an interface to the GNU Recode library. The GNU Recode library converts files between various coded character sets and surface encodings. When this cannot be achieved exactly, it may get rid of the offending characters or fall back on approximations. The library recognises or produces nearly 150 different character sets and is able to convert files between almost any pair. Most » RFC 1345 character sets are supported.

> Замечание: Для Windows-платформ это расширение недоступно.
