For me this returns:
Given font name: Emmentaler-13
Determined font file: /home/harm/.fonts/wds052801.ttf
Actual font in that file: WaltDisneyScript
Given font is present: #f
Given font name: Fancy-Font
Determined font file: /home/harm/.fonts/wds052801.ttf
Actual font in that file: WaltDisneyScript
Given font is present: #f
Again, on an outdated Ubuntu.
