[Zope-dev] z3c.form: unicode error with upload form

Hi, The z3c.form.converter.FileUploadDataConverter has no toWidgetValue() method. Instead, it inherits from BaseDataConverter.toWidgetValue(), that returns unicode(data). However unicode(value) returns an error when the value is binary data! Shouldn't FileUploadDataConverter implement its own toWidgetValue? Christophe
