Bug #4854: Invalid locale_charmap (CP0) when running as Windows Service

• Status: Closed
• Assignee: -
• Target version: 2.0.0
• ruby -v: ruby 1.9.2p136

When ruby process is run as Windows Service the console codepage is not set, GetConsoleCP returns 0.
As a result function rb_locale_charmap refers to not existing codepage: CP0.
It has a dramatic performance drawback on the system when for ex. enumerating through ENV.
The attached patch simple checks if the GetConsoleCP() returns 0 and if so uses the actual system codepage.

• encoding.c (rb_locale_charmap): When ruby process is run as Windows
  Service the console codepage is not set, GetConsoleCP returns 0.
  So on such environment, use GetACP().
