* encoding.c (rb_locale_encoding): should check return value from

	  rb_locale_charmap().

	* ruby.c (locale_encoding): removed.

	* ruby.c (process_options): use rb_locale_encoding() instead of
	  locale_encoding().

	* ext/readline/readline.c (readline_readline): use locale encoding
	  instead of input IO's encoding. [ruby-dev:32872]
