I understand this part.  The part I don't understand is why we do
unification when reading a char from the buffer's text.  That is: why
unify chars in `int' (or Lisp_Object) form but not in the
internal-utf-8 representation?

I would expect the unification to happen during encoding/decoding
only, and not during internal conversions from byte byte-sequence to int.
