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

hash_lookup() function and both mysql and recode have
their own hash_insert function.
The IMAP extension cannot be used in conjuction with
the recode, YAZ or Cyrus extensions. This is due to the fact that they
both share the same internal symbol.
