iconv

I'm running Ruby 1.8.7 with Rails 2.3.5 on Ubuntu 10.04 64-bit. I've written a method that should take a string like this, "École À la Découverte" and output a file-system name like this "ecole_a_la_decouverte":

(Iconv.new('US-ASCII//TRANSLIT', 'utf-8').iconv "École À la Découverte").gsub(/[^\w\s-\â€”]/,'').gsub(/[^\w]|[_]/,' ').split.join('_').downcase

When I test this line in my code, the test always fails saying that "cole_la_dcouverte" is unequal to "ecole_a_la_decouverte". The odd thing is that if I insert a debugger line and use the debugger console the test passes. As well, running this line manually in irb seems to work.

Does anyone know what's going on and why this test is failing? My only thought is that including the debugger or irb somehow adds more support for UTF-8 but I'm at a loss to figure out where to go next.

Thanks in advance!
