NAME
       Encode::Unicode::UTF7 -- UTF-7 encoding

SYNOPSIS
           use Encode qw/encode decode/;
           $utf7 = encode("UTF-7", $utf8);
           $utf8 = decode("UTF-7", $ucs2);

ABSTRACT
       This module implements UTF-7 encoding documented in RFC
       2152.  UTF-7, as its name suggests, is a 7-bit re-encoded
       version of UTF-16BE.  It is designed to be MTA-safe and
       expected to be a standard way to exchange Unicoded mails
       via mails.  But with the advent of UTF-8 and 8-bit
       compliant MTAs, UTF-7 is hardly ever used.

       UTF-7 was not supported by Encode until version 1.95
       because of that.  But Unicode::String, a module by Gisle
       Aas which adds Unicode supports to non-utf8-savvy perl did
       support UTF-7, the UTF-7 support was added so Encode can
       supersede Unicode::String 100%.

In Practice
       When you want to encode Unicode for mails and web pages,
       however, do not use UTF-7 unless you are sure your
       recipients and readers can handle it.  Very few MUAs and
       WWW Browsers support these days (only Mozilla seems to
       support one).  For general cases, use UTF-8 for message
       body and MIME-Header for header instead.
