On a typewriter, I would expect one to type the latin character, hit backspace, and then add the mark? Or if using a typewriter without the necessary mark, just type the latin characters, then add the marks with a pen to the full sheet.

Diacritics usually did not advance paper on typewriters, hence their name "dead keys".
