Description:
------------
If NUL bytes are encoded in the encoded-word, the decoded text
is truncated at that position.
Test script:
---------------
<?php
var_dump(bin2hex(imap_mime_header_decode("=?UTF-8?Q?foo=00bar?=")[0]->text));
var_dump(bin2hex(imap_mime_header_decode("=?UTF-8?B?Zm9vAGJhcg==?=")[0]->text));
?>
Expected result:
----------------
string(14) "666f6f00626172"
string(14) "666f6f00626172"
Actual result:
--------------
string(6) "666f6f"
string(6) "666f6f"
