php can only download the English name of the picture, can not download the Chinese named image how to do?

Php

<?php function Down_file ($file _name, $file _sub_dir) {$file _name=iconv ("Utf-8", "gb2312", $file _name);        $file _path=$_server[' Document_root '). $file _sub_dir. $file _name;            if (!file_exists ($file _path)) {echo "file does not exist";        Return        } $fp =fopen ($file _path, "R");        $file _size=filesize ($file _path);            /*if ($file _size>30) {echo "<script language= ' JavaScript ' >window.alert (' file too large ');</script>";        Return        }*/header ("Content-type:application/octet-stream");        Header ("Accept-ranges:bytes");        Header ("Accept-length: $file _size"); Header ("content-disposition:attachment;        Filename= ". $file _name);        $buffer = 1024;        $file _count=0;            while (!feof ($fp) && $file _size-$file _count>0) {$file _data=fread ($fp, $buffer);            $file _count+= $buffer;        echo $file _data;    } fclose ($FP); } down_file ("Answer.jpg", "/http/");? >

Successful download, open successfully:

Then I put the last sentence in the filedown.php file of the first picture.

Down_file ("Answer.jpg", "/http/");

Change into

Down_file ("answer. jpg", "/http/");

And in the site to change the name of the picture from "answer.jpg" to "answer. JPG", I re-refresh the address:

http://localhost/http/fileDown.php

As a result it gives me a popup dialog box:

Why is the file name not "answer. jpg"? The last download is not a picture ah.
What is the reason, please?

I brainwave, cut the code in the filedown.php file into the EditPlus editor, and then save it to the same location in the site, using the original notepad++ Editor edited by the filedown.php file to cover, this time not only to successfully download, but also open the picture successfully. Make a day, only found that the original is notepad++ editor problem Ah!
