No one.

You are confusing the knowledge of a coding scheme and the intrisinc
information a "coding scheme" *may* have, in a mandatory way, to work
properly. These are conceptualy two different things.

I am convinced you are not conceptually understanding utf-8 very well.
I wrote many times, "utf-8 does not produce bytes, but Unicode Encoding
Units".

A similar coding scheme: iso-6937 . 

Try to write an editor, a text widget, with with a coding
scheme like the Flexible String Represenation. You will
quickly notice, it is impossible (understand correctly).
(You do not need a computer, just a sheet of paper and a pencil)
Hint: what is the character at the caret position?
