Get the unicode icon value from a custom font

Question

I need to write a CSS for an icon font build using the site flaticon. I develop using a MAC with 10.10 and can't find any way to retrieve a single character Unicode value that I need to insert inside my CSS

.font-icon-pencil:before {
    content: "\e038";
}

How can I read the contents of a font file, to get the icon codes within that custom-made font?
