[Debian-l10n-devel] Bug#643008: translate-toolkit: Module zipfileext breaks zipfiles with non-ascii subfiles

[Emmanuel Hainry]

Package: translate-toolkit
Version: 1.9.0-1
Severity: normal

Dear Maintainer,

I use the zipfileext python module from translate-toolkit to modify in place
zip archives. Unfortunately, when a file inside the archive has a
non-ascii name, it fails and worse breaks the archive.

Example:

$ touch blé blï
$ zip test.zip blé blï
$ echo "import translate.misc.zipfileext as zipfileext
zz = zipfileext.ZipFileExt('test.zip', 'a')
zz.close()" | python
Traceback (most recent call last):
  File "<stdin>", line 3, in <module>
  File "/usr/lib/python2.6/dist-packages/translate/misc/zipfileext.py", line 84, in close
    self.writeendrec()
  File "/usr/lib/python2.6/dist-packages/translate/misc/zipfileext.py", line 108, in writeendrec
    self.fp.write(zinfo.filename)
UnicodeEncodeError: 'ascii' codec can't encode character u'\xe9' in position 2: ordinal not in range(128)
Exception UnicodeEncodeError: UnicodeEncodeError('ascii', u'bl\xe9', 2, 3, 'ordinal not in range(128)') in <bound method ZipFileExt.__del__ of <translate.misc.zipfileext.ZipFileExt object at 0x7f3eaa3d1950>> ignored
$ zip -T test.zip
        zip warning: expected 2 entries but found 1

zip error: Zip file structure invalid (test.zip)
