I see "1 characters" here.  I think the result depends on who you type
the above: if there are two characters, a followed by ́, then the file
really has 2 characters, and they are only shown as one on display.
Try "C-u C-x =" to see what you have in the buffer.

I really doubt that: Emacs users tend to think in terms of characters
than in terms of bytes.
