1. There are fonts that include these types of characters. Sometimes that's all the fonts are. Wingdings and Webdings are classic examples. I have a font called Carta (no idea where it came from) that only does road map symbols. Poke around in your fonts and see what you have.
2. Photoshop's Shape tool comes with a load of default bookend shapes. Make sure to load the Ornaments shape library, which is pretty much just bookend shapes. I'm sure you can find other shapes out there, and Illustrator probably has a bunch, too.
