title: Is it bad practice to use unicode symbols or shapes in a  app?
body: <p>There have been a few times where I've used unicode symbols in place of small icons in one of my Cocoa apps, either because it's easier to draw inline with text or because I didn't feel like firing up Photoshop to draw a simple arrow. I've wondered though, could there be issues with localization or fonts I might not be aware of? Are there any cases where these symbols might not match what I'm seeing on my workstation?</p>
