Operating System: Windows XP HE
PHP Version: 5.2.5
New Comment:
Well, maybe it works, but it isn't supposed to work this way, because
the documentation says *nothing* about this:
(PHP 4 >= 4.0.6, PHP 5)
mb_encode_mimeheader -- Encode string for MIME header
Description
string mb_encode_mimeheader ( string str [, string charset [, string
transfer_encoding [, string linefeed [, string indent]]]] )
mb_encode_mimeheader() encodes a given string str by the MIME header
encoding scheme. Returns a converted version of the string represented
in ASCII.
charset specifies the name of the character set in which str is
represented in. The default value is determined by the current NLS
setting (mbstring.language).
transfer_encoding specifies the scheme of MIME encoding. It should be
either "B" (Base64) or "Q" (Quoted-Printable). Falls back to "B" if not
given.
linefeed specifies the EOL (end-of-line) marker with which
mb_encode_mimeheader() performs line-folding (a RFC term, the act of
breaking a line longer than a certain length into multiple lines. The
length is currently hard-coded to 74 characters). Falls back to "\r\n"
(CRLF) if not given.

With also setting mb_internal_encoding(), your example works:
| $str1 = "\xC4\x84\xC4\x8C\xC4\x98\xC4\x96\xC4\xAE"
| $str1 .= "\xC5\xA0\xC5\xB2\xC5\xAA\xC5\xBD";
|
| mb_internal_encoding('UTF-8');
| echo mb_encode_mimeheader($str1, 'UTF-8', 'Q');

Description:
------------
php v5.2.5, mb_encode_mimeheader(), both QP and base64 encoding schemes
incorrectly encodes utf-8 strings.
Reproduce code:
---------------
// $str1 and $str2 characters are in the Latin-Extended-A plane
// $str1 is 'utf-8' string, its base64_encode is:
// 'xITEjMSYxJbErsWgxbLFqsW9'
$str1 = "ĄČĘĖĮŲŪ";
// $str2 is 'utf-8' string, its base64_encode is:
// 'xIXEjcSZxJfEr8WhxbPFq8W+'
$str2 = "ąčęėįųū";
echo mb_encode_mimeheader($str1, 'UTF-8', 'Q');
echo mb_encode_mimeheader($str1, 'UTF-8', 'B');
echo mb_encode_mimeheader($str2, 'UTF-8', 'Q');
echo mb_encode_mimeheader($str2, 'UTF-8', 'B');
Expected result:
----------------
for $str1, QP encoding:
=?UTF-8?Q?=C4=84=C4=8C=C4=98=C4=96=C4=AE=C5=A0=C5=B2=C5=AA=C5=BD?=
for $str1, base64 encoding:
=?UTF-8?B?xITEjMSYxJbErsWgxbLFqsW9?=
for $str2, QP encoding:
=?UTF-8?Q?=C4=85=C4=8D=C4=99=C4=97=C4=AF=C5=A1=C5=B3=C5=AB=C5=BE?=
for $str2, base64 encoding:
=?UTF-8?B?xIXEjcSZxJfEr8WhxbPFq8W+?=
Actual result:
--------------
for $str1, QP encoding:
=?UTF-8?Q?=C3=84=C2=84=C3=84=C2=8C=C3=84=C2=98=C3=84=C2=96=C3=84=C2=AE?=
=?UTF-8?Q?=C3=85=C2=A0=C3=85=C2=B2=C3=85=C2=AA=C3=85=C2=BD?=
for $str1, base64 encoding:
=?UTF-8?B?w4TChMOEwozDhMKYw4TClsOEwq7DhcKgw4XCssOFwqrDhcK9?=
for $str2, QP encoding:
=?UTF-8?Q?=C3=84=C2=85=C3=84=C2=8D=C3=84=C2=99=C3=84=C2=97=C3=84=C2=AF?=
=?UTF-8?Q?=C3=85=C2=A1=C3=85=C2=B3=C3=85=C2=AB=C3=85=C2=BE?=
for $str2, base64 encoding:
=?UTF-8?B?w4TChcOEwo3DhMKZw4TCl8OEwq/DhcKhw4XCs8OFwqvDhcK+?=
