Changing Device Name to 🍟 fails

I've tried but failed ;(

NRF.setAdvertising({}, {name: "🍟"});

And here's what I get in my DevTools:

utf8.js:69 Uncaught Error: Lone surrogate U+D83C is not a scalar value

It would be nice to have at least an error in the IDE.

Why not use TextEncoder Web API there?

PRs welcome... God knows why you'd want to change the name of your Puck to be a square though ;)

If you pre-escaped it you could do NRF.setAdvertising({}, {name: "\xF0\x9F\x8D\x9F"}); I guess? Not sure if that's the correct series of bytes for it though.

NRF.setAdvertising({}, {name: "\xF0\x9F\x8D\x9F"}); works great! Thanks
I can see French Fries now ;)
