UTF-8: Unmasked

NB: This explanation assumes you are familiar with Unicode and differences between Unicode itself and encodings.

When I tried to understand UTF-8, first I read some decoders sources. They use bitwise masks and control flow, which is good for performance, but kind of bad for understanding.

So, here is UTF-8 explanation without masks. (And with PEG.js grammar.)
