Attachment Link Problem in non English Languages

I’m using Advanced Custom Fields plug-in and I have an attachment in my custom fields. I’ve created a field named file and catched the url value inside my static page this way:

$file = get_field('file');
<a href="<?php echo $file['url']; ?>">Download Link</a>

Now everything work well until my file names are in English.
When I upload a persian(farsi) named file (like ???.pdf), the url is correct but download link send me to another page and show me this message: “It looks like nothing was found at this location. Maybe try one of the links below or a search”.

Thanks for any help!
