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 = "ĄČĘĖĮŠŲŪŽ";

// $str2 is 'utf-8' string, its base64_encode is:
// 'xIXEjcSZxJfEr8WhxbPFq8W+'
$str2 = "ąčęėįšųūž"; 

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+?=
