Bug description: mb_encode_mimeheader does not properly escape characters
Description:
------------
At least for Q encoding, this function is unsafe and does not encode
correctly. Raw characters which appear as RFC2047 sequences are simply
left as is.
Ex:
mb_encode_mimeheader( '=?iso-8859-1?q?this=20is=20some=20text?=' );
returns '=?iso-8859-1?q?this=20is=20some=20text?='
The exact same string, which is obviously not the encoding for the source
string. That is, mb_encode_mimeheader does not do any type of escaping.
That is, the following condition is not always true:
mb_decode_mimeheader( mb_encode_mimeheader( $text ) ) == $text
Reproduce code:
---------------
$text = '=?iso-8859-1?q?this=20is=20some=20text?=';
assert( mb_decode_mimeheader( mb_encode_mimeheader( $text ) ) == $text );
Expected result:
----------------
The decode/encode sequence should always return the original text.
Actual result:
--------------
Returned result is different than original (that is, the assertion
fails).
