Not sure what you mean by "consistent unit".

  30.4 Narrowing
  ==============

  "Narrowing" means limiting the text addressable by Emacs editing
  commands to a limited range of characters in a buffer.  The text that
  remains addressable is called the "accessible portion" of the buffer.

Perceiving and treating narrowing as something beyond that can,
indeed, cause conceptual and practical difficulties.  For example,
narrowing the buffer in the middle of bidirectional context will most
of the time completely screw up the text on display.
