Internet-Explorer – IE Unable to download BMP files with Unicode pathname

I have a web application that allows users to upload and download image files by pressing buttons on a web page. Users of this page report that when the file has a Unicode pathname, IE 7 and 8 Unable to download the file. IE will prompt the user to enter a dialog box stating: “Internet Explorer cannot download (file) from (web server).”

The problem only occurs in IE. Unfortunately Yes, I cannot reproduce the problem with these versions on my machine.

My question is, what can cause this, and how can I prevent it from happening? I have read about the issue of cache control (I currently set it to no-cache); however, I am not using HTTP-S, and this issue only occurs for file names that contain Unicode characters.

Update: The problem seems to only happen when the user tries to download the bmp file path. The non-standard file path is downloaded successfully. Could it be Paint that caused the trouble?

The Javascript set attaches an iframe pointing to the URL associated with the file.

Thank you for your latest comment.

This could be:

>Your web server
>Your client’s browser extension
>Your file The name is too long (as shown below, but v old article)

I think it is likely to be number 2, because you can’t reproduce this problem (you are using the real version of the browser, right Not like MultiIEs).

You can run iexplore -extoff to let them start Internet Explorer without extensions and see if there is any difference. They can also check their security settings.

I found in IE that it may be caused by many factors that cause this problem, as I mentioned before, the similar problem of’unable to download’, the reason is that for some reason our server is double compressed content, only IE, IE obviously doesn’t like it that much.
