Subject: [ruby-core:42197] [ruby-trunk - Bug #5917][Open] IO with :binmode => true should use binary encoding


Issue #5917 has been reported by John Firebaugh.

----------------------------------------
Bug #5917: IO with :binmode => true should use binary encoding
https://bugs.ruby-lang.org/issues/5917

Author: John Firebaugh
Status: Open
Priority: Normal
Assignee: 
Category: 
Target version: 
ruby -v: ruby 1.9.3p0 (2011-10-30 revision 33570) [x86_64-darwin10.8.0]


=begin
Binary mode sets the external encoding to binary when specified via the mode string, but not when specified by the :binmode option.

  IO.new(0, 'wb').external_encoding #=> #<Encoding:ASCII-8BIT>
  IO.new(0, 'w', :binmode => true).external_encoding #=> nil

The expected behavior is that :binmode => true should also set the external encoding to binary.
=end
