Fixed compatibility with Ruby 1.8.7 by not interning empty strings.

What was happening was *kinds was creating an array resembling [nil] and so kinds = [:latin] was not being evaluated as the array was not .empty?
What I've done is told the array to compact before checking emptiness and also before looping. This resolves the issue.
