Thanks. I've got my hands on the TTF file.
Apparently, the GSUB tables contains the correct entry for the ft ligature.

The ligature itself doesn't have the correct unicode name. I presume 
this is not a problem when displaying on screen, but my PS handling code 
isn't prepared for the case that glyphs come from outside of the Unicode 
range.

Werner, how I should I display this glyph in PostScript ?
