Cannot read local file with accented characters using PHP file_get_contents

Question

I'm trying to do something simple but it wont let me. I have this code:

$get = file_get_contents("resumé.html");

but I get this error msg:

Warning: file_get_contents(resumé.html): failed to open stream: No such file or directory in C:\wamp\www\mysite\index.php on line 36

It appears I cant open/read files with foreign/accented characters and I dont know why. I tried using functions like mb_convert_encoding() and urlencode() but they dont work..

So how am I supposed to do this without resorting to renaming my file to resume.html?
