I noticed that the BBC on their website called one of the Georgian goal-scorers against Scotland McHedlidze. He is, of course, called მჭედლიძე /mtʃ’edlidze/, so the ch is a digraph, like in China.
It reminds me of a web page I once saw that was selling a book by McHiavelli.
What will be next? Will people start calling certain types of parrots McAws? And will we all start eating McAroni Cheese?
