locale_charmap()

public

Returns the locale charmap name.

Debian GNU/Linux
  LANG=C
    Encoding.locale_charmap  => "ANSI_X3.4-1968"
  LANG=ja_JP.EUC-JP
    Encoding.locale_charmap  => "EUC-JP"

SunOS 5
  LANG=C
    Encoding.locale_charmap  => "646"
  LANG=ja
    Encoding.locale_charmap  => "eucJP"

The result is higly platform dependent. So Encoding.find(Encoding.locale_charmap) may cause an error. If you need some encoding object even for unknown locale, Encoding.find(“locale”) can be used.
