Create font content in css from GULP icon-fonts

Question

I am new to GULP and I really need help here. I am using gulp, first to create fonts from SVGs and then using these fonts to create css file which I use in my page.

This is what I am doing in my css template :

<% _.each(glyphs, function(glyph) { %>
.icon-<%= glyph.fileName %>:before { content: "\<%= glyph.codePoint %>" } 
<% }); %> 

The codepoint is my problem. this is generating the content in this format - "\E100", "\E234" etc.. but I want it to be as "\fxxx".

I am unable to use glyph.unicode[0]..... as it says 0 is not defined error.

Please help. Thanks in advance.
