IE cannot download file with unicode pathname
- by MM
I have a web-app that allows users to upload and download image files by pressing buttons on a web page. A user of this page is reporting that IE 7 and 8 fail to download files when the files have Unicode pathnames. IE prompts the user with a dialog stating: "Internet explorer cannot download (file) at (webserver).". Unfortunately I have not been able to reproduce the problem using these versions on my machine.
My question is, what could cause this, and how can I prevent it from happening? I have read about problems with cache control (I currently have it set to no-cache); however, I am not using HTTP-S, and the problem only occurs with file-names containing Unicode characters.
