I'm not the parent, but I personally can't think of a single instance where I would write "café" instead of "cafe". I can't imagine needing to use a pound, euro, or yen sign either. I'd probably just write pound, euro, or yen if I needed to talk about those currencies. It's a pain to use any of those characters on every device I use so I don't see how any of them could get in the file if I were to adopt this.
