You can test like this:
Test case 1:
In *scratch* buffer, erase the buffer, and choose TeX input method,
input two multibyte characters, such as "«»", which can display in my
emacs. Then change to hexl-mode. Use C-f to move point. You can see
the cursor can't arrive to the last byte. Use C-h v hexl-max-address
to see the value of hexl-max-address. The hexl-max-address is 2 which
is the buffer-size of *scratch*.

Test case 2:
Open a new file, such as /tmp/test.txt. Use C-x RET f to set the file
coding system to utf-16. Input any letters such as "ab", and save the
buffer. Then change mode to hexl-mode. C-h v hexl-max-address show the
value is still 2 which is the buffer-size rather than the sizze of the
file.
