Subject: [ruby-core:66542] [ruby-trunk - Bug #10493] Wrong encoding for	Etc.getlogin in Windows

Issue #10493 has been updated by Usaku NAKAMURA.

Backport changed from 2.0.0: REQUIRED, 2.1: REQUIRED to 2.0.0: DONE, 2.1: REQUIRED

Backported into `ruby_2_0_0` at r48634.

memo:
I changed the patch a little, because 2.0.0 doesn't have rb_w32_wstr_to_mbstr().
2.1 has the function, so I guess it's no problem to backport to 2.1 from trunk.

~~~ruby
name = Etc.getlogin # I've Windows username "D��vis"
puts name           # D���vis
puts name.inspect   # "D\xE2vis"
puts name.encoding  # ASCII-8BIT
name.force_encoding('Windows-1257')
puts name           # D��vis
~~~

As you can see \xE2 isn't "��" in ASCII, but it is for Windws-1257 encoding.
