Subject: [ruby-core:66176] [ruby-trunk - Bug #10493] Wrong encoding for	Etc.getlogin in Windows

Issue #10493 has been updated by D��vis Mos��ns.


No, *Encoding.default_external* is based on current consoles encoding. And by default it is IBM775, but can be different for each opened console. Also it's not related to Encoding which is used by Windows ANSI API. Windows-1257 encoding is set in Control Panel for non-Unicode programs and will be used for all Windows ANSI functions. Proper way is to always use Windows Unicode/Wide API and then it will be encoded with UTF-16.

Thanks for patch, I'll test it when it will be released.

~~~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.
