The single file uploader is not escaping/sanitizing special characters. For example, Mac users’ form submissions fail when they have an apostrophe in their pdf filenames. The error received is:
Whoops, there was a problem with your request!
Please go back and try a different way or contact us if the problem persists.
This may be a server firewall issue. Nevertheless, what would be the best way to escape characters like apostrophes from the single (and multi) file upload inputs?
