I'd advise the author to go one step further and adopt the ANSI layout instead of ISO. So you can just get the US version with most of the keys already etched with the correct symbol, no matter where you are in the world.

Not French, but here's an observation: the French world has great engineering schools like the Polytechniques (Paris, Montreal, Lausanne) or Mines. And the French government historically had military procurement and R&D done inside the country as well. They are, for instance, the only country outside of the United States to have built and operate a nuclear aircraft carrier.
