> 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

supported.

> The Recode library version 3.6 adds weird characters behind converted
strings under certain circumstances. Thus it's safer to use Recode v3.5
or one of the available alternatives like the

>iconv</A
> or
<A
