If the form has two (or more) input fields for uploading files, and if you fill in either field by non-ascii filename and the other field empty, then an UnicodeEncodeError occurs when is_valid() is invoked. To the contrary, no error occurs when (1) the form has only one input field and fill it by non-ascii filename, (2) or the form has two (or more) input fields and fill them all by filenames. (3) or fill one or more input field(s) by ascii filename(s) I wonder why the error occurs only on condition that (4) the form has two (or more) input fields and one field is filled by non-ascii filename and the other field(s) is/are kept empty.
