WARNING: THIS IS A PROOF-OF-CONCEPT. Most functions are incomplete.
All implementation details are subject to change!
This module provide a compatibility layer for <B>Encode.pmB> users on perl
versions earlier than v5.7.1. It translates whatever call it receives
into <B>Text::IconvB>, or (in the future) <B>Unicode::MapUTF8B> to perform
the actual work.
The is_utf8(), _utf8_on() and _utf8_off() calls are performed
by the method native to the perl version 5.6.1 would use
pack/unpack, 5.6.0 uses tr//CU, etc.
Theoretically, it could be backported to 5.005 and earlier, with none of
the unicode-related semantics available, and serves only as a
abstraction layer above Text::Iconv, Unicode::MapUTF8 and possibly
other transcoding modules.
