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