IconFont2Code always tries to use the glyph name (which is stored in the font file) as C# field name.
But not all fonts have glyphs stored with names or with meaningful/descriptive names.

To fix this problem, IconFont2Code allows you select a file which you know it contains meaningful names for the font you loaded.
For example, many fonts used on the web have a .CSS file with meaningful CSS class names for the font glyphs.

Currently, IconFont2Code can try parse glyph names from the following files:
- CSS (.css)
- IconJar (.ijmap)

Check out the following video which shows selecting the CSS file which comes with the Foundation Icon font:
