Of course! Haven’t you ever seen chess problem texts? Check out the Fairy Chess proposal for encoding additional characters. Plenty of examples there. Sorry, I meant “Of course **not**!” that is, chesspiece in a sentence is extremely common, and should be the default (not stylized) form. We can’t repurpose that to be “chesspiece on a white square” because it hasn’t been previously and changing that would affect the layout of existing data. Michael Everson
