Encoding problem

# 1. JRuby source code
# jruby02.rb
require 'java'
include_class 'java.lang.String' do |package,name|
  "J#{name}"
end

ResourceBundle = java.util.ResourceBundle
Locale = java.util.Locale

lang = JString.new 'pt'
country = JString.new 'BR'

cLocale = Locale.new lang, country
msg = ResourceBundle.get_bundle 'MessagesBundle', cLocale

puts msg.get_string 'greetings'
puts msg.get_string 'welcome'

# 2. The MessagesBundle_pt_BR.properties is 
# in the same folder as the jruby02.rb program
# MessagesBundle_pt_BR.properties
greetings = Ol\u00a0
welcome = Benvindo ao Brazil

# 3. Executed the program
# jruby jruby02.rb
# and the output is
Ol 
Benvindo ao Brazil

# whereas the outputs should have been:
Olá
Benvindo ao Brazil

# The equivalent Java program works properly
