[imp] Subject encoding issue

[qmail at top-consulting.net]

The issue of the '?' characters has now also been solved. Not sure if  
it's just our systems or everyone out there that has this problem but  
we made the following change in imp/mailbox.php

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

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

Doing this, also no longer requires the modification to  
NLS::getCharset() I mentioned earlier since the subject effectively is  
UTF8 now and the function works properly.

Cheers

I guess it could be done in one line as well
