[Bug 1199239] [NEW] Do not call isprint when listing

[Ma Xiaojun]

Public bug reported:

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.
