ext::Encode::lib:Perloext::Encode::lib::Encode::Unicode::UTF7(3p)NAMEEncode::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 reci-
pients 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.
