Description

From http://redmine.ruby-lang.org/issues/show/4340

The example script there behaves differently inconsistently on JRuby 

~/projects/jruby ➔ jruby --1.9 t.rb
using gsub
"Hello Everybody!"
#<Encoding:ASCII-8BIT>
"Hi World!"
#<Encoding:ASCII-8BIT>
using sub
"Hello Everybody!"
#<Encoding:UTF-8>
"Hi World!"
#<Encoding:UTF-8>

It appears to be using the pattern's encoding in gsub and the original's encoding in sub (and our pattern's encoding is wrong due to other issues).

This is not in 1.9.2 yet and we can keep track of this issue for 1.9.3.

Looks like we match 1.9.2 now, but 1.9.3 is different. Hooray!

system ~/projects/jruby $ jruby --1.9 t.rb 
using gsub
"Hello Everybody!"
#<Encoding:UTF-8>
"Hi World!"
#<Encoding:US-ASCII>
using sub
"Hello Everybody!"
#<Encoding:UTF-8>
"Hi World!"
#<Encoding:UTF-8>

system ~/projects/jruby $ ruby1.9.2 t.rb 
using gsub
"Hello Everybody!"
#<Encoding:UTF-8>
"Hi World!"
#<Encoding:US-ASCII>
using sub
"Hello Everybody!"
#<Encoding:UTF-8>
"Hi World!"
#<Encoding:UTF-8>

system ~/projects/jruby $ rvm 1.9.3 do ruby t.rb 
using gsub
"Hello Everybody!"
#<Encoding:UTF-8>
"Hi World!"
#<Encoding:UTF-8>
using sub
"Hello Everybody!"
#<Encoding:UTF-8>
"Hi World!"
#<Encoding:UTF-8>

Both 1.6 head and 1.9.3 agree now with all UTF-8 values (master as well). Resolving.
