hmm, did you get "'=?UTF-8?B?cHl0aG9uILLiytTTyrz+?='" by mb_encode_mimeheader,  if not plz check the original text before encoding.

after you double check it, if you still believe this is a bug of PHP, plz supply the encoding script, then change the bug status from Feedback to Open again.

The text is not encoded by mb_encode_mimeheader, but generated by a python 
sendmail script. I checked the decoded string again and found that the source 
string's charset may be GB2312 and was marked UTF-8 by encoder. So i choose to 
close this bug and sorry for this mistake.
