Bug #11519

Updated by nobu (Nobuyoshi Nakada) almost 5 years ago

~~~ruby ~~~ 
 #! /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 
 puts "#{bar}#{foo}".encoding 
 ~~~ 

 The output for this on all versions of ruby that I have except 1.9.1 is this: 

 ~~~ 
 Ruby version: 2.2.3 
 __ENCODING__ = UTF-8 
 UTF-8 
 UTF-8 
 UTF-8 
 US-ASCII 
 US-ASCII 
 US-ASCII 
 ~~~ 

 It is the last part that gave me grief.    Rails `content_for` content_for used such a construct so all my content was being converted to US-ASCII and sometimes were error off. 

 It seems to me the `"#{ "#{ ... }"` }" string should be utf-8 and so anything inserted into it should be converted to utf-8 so `"#{nil}"` "#{nil}" should be utf-8 -- not US-ASCII.
