So I am trying to check if a pdf file exists on my server or not. 

PDF files are named in korean like abc.com/토보토보.pdf 

I have tried :

```
function UrlExists(url)
{
    var http = new XMLHttpRequest();
    http.open('HEAD', url, false);
    http.send();
    console.log(http.status);
}

```

But the problem is it always encoded to *example.com/%C3%AD%C2%86%C2%A0%C3%AB%C2%B3%C2%B4%C3%AD%C2%86%C2%A0%C3%AB%C2%B3%C2%B4.pdf*

```
UrlExists("example.com/토보토보.pdf")
01:51:29.144 VM428:14 
HEAD
http://example.com/%ED%86%A0%EB%B3%B4%ED%86%A0%EB%B3%B4.pdf     
404     (Not Found)

```

How do i get the solution to my problem?
