When I used multipart/form-data, I find that:

1. Content-Type: multipart/form-data;  
boundary=----------------------------4db878605894\r\n
2. Content-Type: multipart/form-data;  
boundary=----------------------------4db878605894; charset=utf-8\r\n
3. Content-Type: multipart/form-data; charset=utf-8;  
boundary=----------------------------4db878605894\r\n

in above three example, when I submit 1 and 3, It’s work fine, but 2  
don’t  
work

Is there a bug? or who can tell me why?

demonstrate code: [\<?php$header = \<\<\<heredocPOST /index.php HTTP/1.1\r\nUser-Agent: curl/7.21.4 - Pastebin.com](http://pastebin.com/59aAhkFY)
