I'm currently trying to format text printers, but I have ran into another issue. Any time the dialogue contains an apostrophe like "father's" or "wasn't" the apostrophe shows as ?. is there any way to fix this?

It's likely related to the font you're using.

I am using the default text that NaniNovel uses. I have not changed anything with the text.

I managed to figure out what was going on. In case anyone else experiences the same problem. When I copied my dialogue from the Google Doc. I was using I’d instead of I'd.
