Nice link. It seems that Prof^H^H^H^H Mr Unwin's texts and the Lear letter I quoted are in different languages. Compare 1 and 2:

1. Are you sitting comfort-boldly, two-square on your botty?

2. Okul scratchabibblebongibo, viddle squibble tog-a-tog, ferrymoyassity amsky flamsky ramsky damsky crocklefether squiggs.

There's seems to be more content in 1 than in 2. Listening to Unwinese would not tire one as quickly as Learese. &c.

As for Shakespeare, have you ever seen his penmanship? Unbelievable. I think Shakespeare was England's finest dictator.
