As a webdeveloper have you ever wondered how a special character has to be encoded as a html entity? There is a nice little tool available online that will answer your call for help. What makes the tool really rock is the simplicity and great incremental search. Typing in the letter ‘c’ will present you entities for “cent”, “copyright”, the greek “sigma” and mathematical entities like “superset” because the basic shape of the resulting special character is also considered. Upon entering a ‘b’ you will get the german ß as one of the results.This kind of search is almost a “do what I mean” feature and very helpful if you do not know exact substrings or meaning of your special character.
There is a Firefox-Extension and as a special goodie for our beloved Mac-users there is even a dashboard widget available that works without internet connection and is a bit more convenient to use than the web application.
