-=head1 NAME
-
-Encode::Unicode::UTF7 -- UTF-7 encoding
-
-=head1 SYNOPSIS
-
- use Encode qw/encode decode/;
- $utf7 = encode("UTF-7", $utf8);
- $utf8 = decode("UTF-7", $ucs2);
-
-=head1 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%.
-
-=head1 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.
