Description:

When we download an attachment file, the dialog box appears and opens the file based on the application associated with the file extension. If the filename has double byte characters, the filename in the title bar on application becomes garbled. Also, if we try to save the file using 'Save As', the filename on the dialog box is also garbled.

Solution:

When we download an attachment file, the dialog box appears and opens the file based on the application associated with the file extension. If the filename has double byte characters, the filename in the title bar on application becomes garbled.

Also, if we try to save the file using 'Save As', the filename on the dialog box is also garbled.

This behavior is known problem with Internet Explorer 6 and 7. When the browser downloads the double byte file, the file will be cached with the UTF8 encoded filename. The browser needs to decode the encoded filename when the download is completed. However, IE6 and IE7 don't have the decode feature by design. This is why the problem occurs.

Mozilla Firefox and Internet Explorer 8 do have the decode feature so, this problem does not occur is the user is using Firefox or IE8.
