The author of this article doesn't seem to realize that a Unicode character is harder to enter than an image. For example, on Microsoft Windows, it appears that you would have to: 1. Google "enter unicode character" 2. Read http://en.wikipedia.org/wiki/Unicode_input http://en.wikipedia.org/wiki/Unicode_input all the way down to the "Hexadecimal input" section 3. Manually set a registry key 4. Reboot your system 5. Correctly convert 243 to hexadecimal 6. Hold the Alt key, press + on the numeric keypad, and then enter the desired hexadecimal value. Inserting an image is something that people are much more likely to already know, or be able to easily figure out.
