--- Comment #5 from Parag pnemade@redhat.com --- fntsample shows only glyphs which have Unicode code points and not extra glyphs given in the font. See the description given on upstream page
"FntSample is a tool that can be used to make font samples that show coverage of the font and are similar in appearance to Unicode Charts."
So the output in pdf is similar to Unicode charts.
