Benoit Tellier commented on MIME4J-250:
---------------------------------------

Got the issue. I bet the Q encoding can be normalized after unfolding.

I will have a look today, it looks fun!


{code:java}
    @Test
    public void test() throws Exception {
        DefaultMessageBuilder messageBuilder = new DefaultMessageBuilder();
        messageBuilder.setMimeEntityConfig(MimeConfig.PERMISSIVE);
        messageBuilder.setDecodeMonitor(DecodeMonitor.SILENT);

        final Message message = messageBuilder.parseMessage(new 
ByteArrayInputStream(("Subject: Re: 
=?UTF-8?Q?=D8=AA=D8=B2_=D8=A2=D9=82=D8=A7=DB=8C_=DA=A9=D8=B1=D8=A7=D9=85=D8=AA=DB=8C?=\r\n").getBytes()));

        System.out.println(message.getSubject());
    }
{code}

Returns

But


{code:java}
    @Test
    public void test() throws Exception {
        DefaultMessageBuilder messageBuilder = new DefaultMessageBuilder();
        messageBuilder.setMimeEntityConfig(MimeConfig.PERMISSIVE);
        messageBuilder.setDecodeMonitor(DecodeMonitor.SILENT);

        final Message message = messageBuilder.parseMessage(new 
ByteArrayInputStream(("Subject: Re: 
=?UTF-8?Q?=D8=AA=D8=B2_=D8=A2=D9=82=D8=A7=DB=8C_=DA=A9=D8=B1=D8=A7=D9?=\r\n" +
            " =?UTF-8?Q?=85=D8=AA=DB=8C?=\r\n").getBytes()));

        System.out.println(message.getSubject());
    }
{code}

Returns


{code:java}
Re: تز آقای کرا��تی

I also hereby acknowledge Thunderbird handles the splited encoding correctly... 
(I manually changed the subject of an email to check.)

> when decoding a multi line subject a problem occurring, assume that we have:

>  =?UTF-8?Q?=85=D8=AA=DB=8C?=`
> after decoding the result is: `Re:  تز آقای کرا��تی`
> half of unicode \uD985 is in the end of line 2 and half in beginning of line 
> 3.
> Thunderbird, gmail,... have no problem with this email and show the subject
