keyboard-characters-uncommon

Matt posted this link to ⌘C ⌘V Character (Copy-Paste Character), a site that gives you easy access to the most commonly used special characters that you might not necessarily remember the keyboard codes for. There are some characters included on that site that make me wonder why anybody would want to use that particular character. I mean, seriously, is the snowman with a hat really one of the most “commonly used” characters?
