Wrong. This is obviously a proportional font, which did not exist in 1912. It seems to have been transcribed from an original 1912 document to a post-1970s word processor or typewriter, which is what is shown in the link above. I am betting the original did not have typos.
An atlas I had as a kid had spelled it Rumania. I’m guessing it was published in the 1960’s, maybe earlier.
By 1976 with Nadia Comenici winning medals, news outlets were spelling it as Romania.
I haven’t seen it as Roumania but I’d have to check some old atlases.
