After you see then correctly in the buffer do:

C-x ret c utf-8

then

C-x C-s

Now next time you load that file it should appear correctly.
ā  and ī are not in iso-8859-1 and so you must use a more comprehensive 
coding system.

If you use utf-8 a lot you can put ;; -*- coding: utf-8[;] -*- into the 
first line of the file. I don't know whether that sem in brackets is 
needed or not.
