1020615 - Ensure file names inside a packaged app are valid

Status: RESOLVED WONTFIX

(Marketplace Graveyard :: Validation, defect, P2)

Description

[Andy McKay]

The app in bug 1013347 didn't sign properly because of issues handling utf-8 filenames in the signing code. But it doesn't point out that file names should be ascii or utf-8 as noted in:

http://www.pkware.com/documents/casestudies/APPNOTE.TXT

Bit 11: Language encoding flag (EFS).  If this bit is set,
                the filename and comment fields for this file
                MUST be encoded using UTF-8. (see APPENDIX D)

Given that, we should check that all the filenames are valid utf-8 before they get to signing, I'm guessing a valid encode/decode in python will do the trick. I'm not sure how important it is to do this, is it possible to generate a zip with invalidly encoded filenames?
