Simplify characters iteration

[ebraminio]

Just to illustrate the issue better,

let text = '👌'; for (let i = 0; i < text.length; i += 1) { console.log(text[i]); } // FAIL: prints two incorrect characters [...text].forEach(c => console.log(c)) // PASS: prints one character for (const c of [...text]) { console.log(c); } // PASS for (const c of text) { console.log(c); } // PASS

Also curious to know why https://github.com/papandreou/subset-font/commit/84ac1955987f5197b0f037d6cf0dde1622d73397 was needed yet this won't revert that and just simplifies it.

Ah, you're right that the spread isn't necessary, thanks 🎉

I added 84ac195 because forEach is "old school" now that we have for...of, not because there was a functional problem with it.
