Bug description:
  [ Impact ]

   * zip in noble is built with _FORTIFY_SOURCE=3 and the code is bug
  with buffer overflow when filename contains non ascii characters. So
  it crashes at runtime.

  [ Test Plan ]

   * install zip from proposed
   * run following commands:
     touch ä
     zip x.zip ä
   * It shouldn't crash.

  [ Where problems could occur ]

   * The patch has been included in fedora 40 and tested there.
   * If the patch is still wrong to calculate the buffer size, zip continues to crash.

  [ Other Info ]

   * None

  Steps to reproduce: command line
  $ touch ä
  $ zip x.zip ä

  will result in
