I have a strong need in a Windows utility like Character Map with a feature of showing CSS classes for the characters. 

That's because I use icon libraries e.g. Ionicons or Font Awesome in my designs and need to search for the css class for every single icon I used when transferring specs to the developer. 

It's not handy to look for it every time in browser so I guess it should be a dedicated utility I'm not familiar with. If somebody could suggest what utility to use, it would be extremely helpful! 

Here is a screenshot if I was not clear enough[![enter image description here][1]][1]
