Noticed an interesting ChangeLog entry from yesterday on
ruby_1_9_2 branch:

Mon May 17 11:09:58 2010  NAKAMURA Usaku  <usa@ruby-lang.org>

        merge from trunk (r27856, r27857)

        * lib/fileutils.rb (FileUtils::Entry_#entries): returns pathname in
          UTF-8 on Windows to allow FileUtils accessing all pathnames
          internally.

Would this approach also be considered for Dir.pwd:

  result = Dir.pwd(:encoding => "UTF-8")

?


If so, I already have the rb_w32_ugetcwd implementation (presented
in [ruby-core:30052] ).

I would be happy to provide a patch for Dir.pwd if this is
acceptable.
