I just realized that encoding the subject to UTF8 also fixes the  
NLS::getCharset() 'bug' I noticed earlier. Since the subject is  
already UTF8 there's no need to have that function return ISO-8859-1

The modified line in mailbox.php simply has to look like:

$msg['subject'] = utf8_encode($imp_ui->getSubject($ob->subject));
