There isn't a specification to my knowledge on the specific language used
to count the numbers, although in this case Kawa is an oddity. I attached a
patch to fix that. The testsuite errors for me from a fresh git clone and
it's been a while since I've contributed, so I don't know if it breaks in
other areas aside from the obvious formatting cases.

I don't know, but I would guess it's another under specified area, for the
the english number formatting in particular,


  // Inspired by the Slib version, which is inspired
