Unicode characters in irb on OS X

I noticed that my RVM-handled irb in OS X (Mountain Lion) didn't like Norwegian characters today. So instead of an 'ø', I got '\U+FFC3\U+FFB8' during entry, and nothing afterwards. Like so:

	a = ["test", "tull", "t\U+FFC3\U+FFB8ys"]
	=> ["test", "tull", "tys"]

Not really satisfactory. After googling: "os x irb unicode characters rvm" I found the answer on stackoverflow.

Almost.

My adapted solution was this:

	$ rvm get latest
	$ rvm pkg install readline --verify-downloads 1
	$ rvm reinstall all --force --verify-downloads 1

So now I can do:

	a = ["test", "tull", "tøys"]
	=> ["test", "tull", "tøys"]

Better.

(Not quite sure why the '--verify-downloads 1' part is needed, but it did the trick.)
