By the way, if you're on Windows, don't neglect the Character Map tool! You can find it under Start>Programs>Accessories>System Tools>Character Map

It will show you all of the glyphs in a font and allow you to copy a selected glyph to the clipboard. I find that very few people even know that it's there, but it's tremendously useful whenever you need to type the trademark symbol ™ or some other not-often-used character.
