Hi,

I'm using Ruby 1.8.6, and I just discovered something rather
interesting, here is a test:

require 'test/unit'

class TestRegexBug < Test::Unit::TestCase

  def test_bug

    hours = "pon-¥È¹Æt"

    assert(hours =~ /[¥È¹¾et/i)
    assert(hours =~ /¥È¹Æt/i)
    assert(hours =~ /-¥È¹Æt/i)
    assert(hours =~ /[c¥È¹¾et/i)
    assert(hours =~ /-[¥È¹¾et/i)

  end

end

As you can see, this only happens with unicode letters... (the last test
fails).. I'm used to the fact that //i doesn't work for unicode chars
and I already know that you need two dots to match one of these.. But
this problem is different and weirder, because what triggers it is a
minus sign before the square brackets.. if you remove either the '-' or
'[]' from the regex, it works..

Can you comment?

thank you,
david
