It should be

%e5%b7%a7%e8%99%8e%e5%bf%ab%e4%b9%90%e7%89%882008%e5%b9%b412%e6%9c 
%88%e5%8f%b7DVD0812.iso

instead, if I'm not mistaken.

E.g. UTF-8 + Percent-encoding (aka URL encoding) [1]

That said, because this data came via a HTML <form>, it might have  
been encoded using the form's accept-charset instead of UTF-8:

(1) Percent decode the file name
(2) Convert the resulting byte stream into an Unicode representation  
using the appropriate character set encoding

Nothing to do with nginx though....

HTH.
