Alex Lindsay's pick of the week on MacBreak Weekly episode 392 is Ultra Character Map for the Mac. This shows you all of your fonts, and even gives you a real time preview of what a word or phrase would look like as you type it. Then you can see side-by-side comparisons by scrolling through the font options.
Ultra Character Map gives you access to characters and glyphs within some fonts that can't be produced with the keyboard. The app is easy to use, and lets you find fonts by filtering them by name, collection, classification and more. It also will give you detailed font information, such as keystroke combinations to produce special characters. This is a powerful alternative to built-in character map built into Mac OS X.
