[Bug 1199239] Re: [SRU] unzip list utf-8 (non-ascii) filenames as ??

[Brian Murray]

Hello Ma, or anyone else affected,

Accepted unzip into raring-proposed. The package will build now and be
available at http://launchpad.net/ubuntu/+source/unzip/6.0-8ubuntu2 in a
few hours, and then in the -proposed repository.

Please help us by testing this new package.  See
https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to
enable and use -proposed.  Your feedback will aid us getting this update
out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug,
mentioning the version of the package you tested, and change the tag
from verification-needed to verification-done. If it does not fix the
bug for you, please add a comment stating that, and change the tag to
verification-failed.  In either case, details of your testing will help
us make a better decision.

Further information regarding the verification process can be found at
https://wiki.ubuntu.com/QATeam/PerformingSRUVerification .  Thank you in
advance!

  [SRU] unzip list utf-8 (non-ascii) filenames as ??

Bug description:
  [Impact]
  Despite notorious LP #580961 , the biggest issue of current unzip is that it always list non-ASCII file name character as question mark (?) .

  Even though handling Zip archives with non-standard encoding (neither
  CP437 nor UTF-8) can be tricky, we should support UTF-8 Zip archives
  out of the box as it's the standard and it become more and more
  popular now.

  Newer version of unzip in Debian and Ubuntu (13.10+) fixed the issue
  by changing build configuration already. The fix is visible to File
  Roller and Ark also.

  The issue remains in 12.04 - 13.04 currently. We need to apply the
  same fix for them.

  [Test Case]
  touch naïve.txt
  touch 天真.txt
  zip test.zip naïve.txt 天真.txt
  unzip -l test.zip

  With unzip -l you should not see question marks in the filenames.

  ark test.zip
  file-roller test.zip # the result may be different see notes below

  [Regression Potential]
  Little, if any, as the proposed fix is used by Debian, Ubuntu 13.10+ and openSUSE (using a different approach to archive exactly same effect) already.

  [Other Info]
  The fix for this bug also fixes bug 580961, however that bug had so much history I (bdmurray) decided not to make one the duplicate of the other and just also include that bug number in the changelog.

  Note that Ark is the better frontend software for testing, as it seems
  to use unzip backend exclusively. File roller, on the other hand, will
  use 7z backend when 7z exists, so the issue can magically disappear
  some time (7z support utf8 filenames correctly). 7z isn't included on
  the ISO, though.
