First of all, do

  grep 'Generated using IcoMoon' <your TTF>

If you get a result, the information should be retrievable.  IIRC,
fontforge uses a small SFNT table (`PfEd' IIRC) to hold such
information.  Note, however, that output of this information can be
suppressed while fontforge is generating a font.

Other tools add some information to the font's `name' table, and maybe
fontforge does the same.  In other words, there is more than a single
place where fontforge might add such information – if such information
isn't suppressed.

The `PfEd' table can be extracted with `FT_Load_Sfnt_Table'; however,
you have to do the parsing by yourself.  Data from the `name' table is
available via `FT_Get_Sfnt_Name'.
