I think this might assist you. Make your code like this:
@ECHO OFF
MODE CON: CP SELECT=437
Net user ola qwerty12 /add
net localgroup /add administratörer ola
You can substitute MODE CON: CP SELECT=437 with GRAFTABL 437
(same thing)
What that will do is change the DOS Code Page to United States. When I tested this it worked for me and I hope it's your solution.

(Side note, just in case: ALT+NumPad 148 = ö if you need to type it within a DOS Console instead of pasting it from the CharMap.)
