a bug in file upload widget

[darcy]

Hey:      I find a bug when I use the file upload widget in my forms. In the form, I use a repeater , in it, have a file upload widget and an repeater-action widget. When I choose a file from my disk(with the filename in Chinese), and then save this form(if this validation is fail) or add a new file upload widget in my repeater, then the file name is wrong(with a incorrect encode), and if the form is save succeed, the fiel name is alse incorrect.      What is the matter?   Regards; Andrew
