This is probably related to browser CompositionEvent events not being properly handled or are not consistent across browsers.

Thanks for all this testing of the keyboard. I will look into inconsistencies with the inputs, and will also check on composition events which I actually dind't know about.

Indeed js-dos not having a keyboard is known, I plan to redo js-dos to the latest version which will add back in support for mobile.
