One of these services is the online tool named Symbol, that is a simple free web application which allows you to pick any type of symbol character available in the collection. Then you can just copy and paste it in your document or even PowerPoint presentations.
The collection includes lot of different symbols and characters in an icon style, that you can download for free.
