Fonts messed up all symbols

The site looks perfectly fine to me, but one other person is saying the fonts are all like symbols – see this screenshot.

Site is https://standrewstaxiservices.co.uk/

I don’t think this is a WP issue as the site looks perfect to me, more likely his browser, but anyone got any pointers?
