Just got reminded of a much earlier Window SWF I made. This one allows you to paste in any character and it will show you the unicode value for that character. Or, vice versa, enter a unicode number and see the character. Thought I had blogged this one earlier, but not, so here it is.

Again, save to your WindowSWF directory, and restart Flash and open as an “Other Panel”.
