Question

The following program works well with ruby but gives me a problem with JRuby when reaching a file with a special character like the one I am using for testing, called “mão.txt”:

# coding: utf-8

puts "(A) #{__ENCODING__}"

puts "(B)" + "".encoding.to_s
puts "(C)" + String.new.encoding.to_s

Dir.glob("./fixtures/*").each do |f|
    puts "(D)" + f.encoding.to_s + "  " + f
    File.open(f)
    g = File.expand_path(f)
    puts "(E)" + g + " " + g.encoding.to_s
    File.open(g)
end

The result with JRuby is:

(A) UTF-8
(B)UTF-8
(C)ASCII-8BIT
(D)ASCII-8BIT  ./fixtures/mão.txt~
Errno::ENOENT: No such file or directory - ./fixtures/mão.txt~
  initialize at org/jruby/RubyFile.java:315
        open at org/jruby/RubyIO.java:1176
      (root) at encoding.rb:10
        each at org/jruby/RubyArray.java:1612
      (root) at encoding.rb:8

I am using Ubuntu 12.10, JRuby 1.7.0 and java 1.7.0_09

I plan to have the application packaged with Warble, so I fear command line arguments are not an option.

Answer 1

This is a reported bug with Dir.glob.
