Usually as part of a heading / sub-heading, you can often see symbols like in the image below on either side of the text:
I don't mean these symbols specifically, just the general name for these symbols that illustrate that some text is important in a way. Another example is tildes on either side of a phrase. It's been on my mind for embarrassingly long, and none of my web searches prove to be helpful.
The reason I ask: I'm trying to make a food menu that looks like those you see in a diner or the like. I'm pretty sure adding these types of symbols will make it look aesthetically pleasing, but I don't know how to search for this design inspiration without knowing what to call it.
