The same bytes have the same number of bytes, whether you interpret
them as having one encoding or some other encoding.  How many
characters these bytes have depends on the encoding.

Of course, if you have transcoded the bytes into some other encoding,
you have to transcode them back for counting.  So for Emacs this means
converting back to the input encoding, and then counting (i.e., what
you describe as TRT (which I guess means The Right Thing)).
