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 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.
