Bug #8789

File.expand_path(File.dirname(__FILE__)) return wrong encoded result

Added by 贾 延平 over 2 years ago. Updated almost 2 years ago.

ruby -v:ruby 2.1.0dev (2013-08-10 trunk 42491) [i386-mingw32] Backport:1.9.3: UNKNOWN, 2.0.0: UNKNOWN


A test.rb in a nonascii path with the follow content:
(({puts File.expand_path(File.dirname(FILE)).encoding}))
Run it with utf-8 as internal encoding.
expect result: UTF-8
actual result:US-ASCII

Tested on windows 7.

I submited a patch to fix this problem but in a wrong way, check it(https://bugs.ruby-lang.org/issues/8774), hope it can help to fix this problem.
