Decoding UTF-8 in an e-mail

I am trying to extract data from an e-mail which is utf-8 encoded in perl

In particular I need to read the subject line:
Subject: =?utf-8?B?SU5WRU5UT1JZIERFUExFVEVE?=

I'm pretty sure that I need to use the Encode.pm module but I just can't get it to work.

Your string doesn't look like utf-8.  It looks like base64, but with some extra stuff.  Here is a script that'll convert it.

use MIME::Base64::Perl;
my $Subject = '=?utf-8?B?SU5WRU5UT1JZIERFUExFVEVE?=';
print "Subject: $Subject\n";
$Subject = DecodeSubject($Subject);
print "Subject: $Subject\n";
sub DecodeSubject {
	my $s=shift;
	$s =~ s/^=\?utf-8\?B\?(.*)\?=$/$1/s;
	return decode_base64($s);

Works a treat. Thank you very much.

I think I'm a bit confused between Character Sets and Encoding. I need to o a bit more reading!
