[Bug 1199239] Re: Do not call isprint when listing

[Ma Xiaojun]

** Description changed:

  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 become more and more popular now.
  
- The attached patch is from openSUSE unzip patchset and it solves the
- file name question mark problem. The fix is visible to File Roller also.
+ Newer version of unzip in Debian and Ubuntu (13.10+) fixed the issue by
+ change build configuration already. The fix is visible to File Roller
+ also. The issue remains in 12.04 - 13.04 currently.

** Summary changed:

- Do not call isprint when listing
+ unzip list utf-8 (non-ascii) filenames as ??, also affects file roller and ark

** Summary changed:

- unzip list utf-8 (non-ascii) filenames as ??, also affects file roller and ark
