I recently been messing around with google translator out of boredom. Then came the point where I entered some names from Interesting Times. When 'Lotus Blossom' turned out to be 'Han' I didn't think much of it. But then, when Pretty Butterfly came with a certain possible translation, I called a friend to ask him if that actually works as a legit name and if it is pronounced as i thought it was. He said it works.
The translation in question?
Xiu Die...pronounced 'Chewie'....
I tip my hat to you, Sir Terry.
