** Description changed:

  Binary package hint: unzip
  
  This is a fairly annoying bug that's been around and known at least
  since 2005.  It's very visible as it will very often make exchange of
  zip files with Windows users impossible, for example.  As such, it
  gathered it's fair share of "me too" and "how dare you haven't fixed
  this yet!!111!" comments.
  
  Problem description:
  zip/unzip and the specification fall short when dealing with non-ASCII filenames not encoded in UTF-8
  
  test case:
  do an "unzip -l" on the file http://tinyurl.com/2aofpxs and witness the question marks
  
  affected programs:
  the problem is in unzip itself, but affects GUI like xarchiver, file-roller, etc. that rely on unzip for the decompression
  
  suggested solutions (most are workarounds, not proper fixes):
-  a) reintroduce patch for codepage-based zip filenames: bug 477755
+  a) reintroduce patch for codepage-based zip filenames: bug 477755, http://tinyurl.com/2aqdbqg (Ubuntu blueprint)
   b) unzip filename according to locale: bug 203609
   c) Ubuntu JP has a patch, probably not generally applicable, bug 269482
   d) Russian altlinux distro uses natspec lib and patched zip binary
  
  natspec was mentioned in bug 477755 comment #2 and may indeed be a
- proper fix, needs closer inspection (I haven't really looked, yet.

  It's unfortunate the FOSS community so far hasn't been able to fix this
  rather visible problem.  I'm opening this ticket as a master bug and
  clean slate to document the issue and current status.  Please don't ruin
  it by making above-mentioned unhelpful comments, they actually slow
  things down!  Please don't nominate for a release.
  
  Unless you're a dev and can provide a patch, you should think VERY
  carefully to do anything but
  
  1) subscribe yourself to this ticket
  2) mark this bug as affecting you
  3) tell me via mail about other bugs you think are a duplicate of this one, discussing the same problem
  
  1) to 3) will showcase to the devs how many people are affected and that
  is the only real chance we have for somebody to take a serious look.
  "Me too" comments do the opposite, so again, please don't do it.
