Windows version - select fonts -- how do I know it is working

I am wondering how I can use custom fonts with the Windows version. I go to tools->general options, and fill out Editor font family with the name of the font, something like “iA Writer Mono S,” but for some reason, it does not seem to have any effect.

How do I get confirmation that it is working?

I’m not sure, but you might have to restart Joplin for the font change to take effect?
