[ruby-core:70693] Possible encoding bug

Hi,
I’ve been tracking down a bug in Rails but finally came done to what might be a bug in Ruby.
Here is my sample code:
===================
#! /usr/bin/env ruby
# encoding: utf-8
puts "Ruby version: #{RUBY_VERSION}"
puts "__ENCODING__ = #{__ENCODING__}"
puts "hello".encoding
foo = "hello"
puts "#{foo}".encoding
puts "#{"hello"}".encoding
bar = nil
puts "#{bar}".encoding
puts "#{nil}".encoding
===================
The short of it is for all versions of Ruby except 1.9.1 that I tested (including the latest 2.2.3)
bar = nil
“#{bar}”.encoding => US-ASCII
which seems inconsistent to me. In Ruby 1.9.1 it is UTF-8
Here is the output from the program above with various versions of Ruby
Ruby version: 1.9.1
__ENCODING__ = UTF-8
