Thanks for your suggestion. I hadn't thought to look there, but just did. The link is to a font for displaying the correct roman alphabet symbols that are needed in addition to the regular ones (letters with curved lines underneath or superscripts). So, not the cuneiform symbols, which are the ones the article uses!
But you got me looking around and trying again to follow Wikipedia's own help page on special characters, which I had previously found very frustrating and of no help whatsoever. (You have to already know more than I do to understand what they're talking about.)
Turns out, I had given up too early, after finding nothing that would work in the articles sections on entering special characters (not relevant to me), viewing, and displaying special characters. So I hadn't previously seen that there is also a section on ancient scripts a lot further along down the page.
That section is also not easy to use, but I managed to find a font with the right characters and install it, and now they show up.
Many thanks for nudging me along in the right direction.
