And it turns out they failed to provide for a combination or two -- I
think it was resh with hirik under it that couldn't be set with the old
WorldScript I system. I don't know whether OS X has fixed this; with OS
9, or 9.2 which includes all the Language Kits, after the demise of
WorldScript, there doesn't seem to have been any provision for RtoL
scripts.
