As others stated, that's because each newline is counted as 1 character
too.

No, it contains 8 characters:

1. f
2. o
3. o
4. Newline (Just 1 character, does not matter if it is 1 byte on unix or 2
bytes on Windows. This is character count, not byte count.)
5. b
6. a
7. r
8. Newline

As I wrote, in Windows Emacs uses DOS style, more precisely 'utf-8-dos'.

As written about emacs sees the newline as just 1 character. Emacs is
printing character count, while ls is printing byte count, and thus the
difference.

Visualize that newline character as just 1 character as the "\n" used in
regexps to match newlines.

As explained above.
