But the concept of /UniqueID has been abandonded by Adobe a very long
time ago:


(This link is from 2006.)  So it's actually another bug if pdftex
relies on it.

As I've already mentioned: Use the font's version (1.05 vs. 1.06 in
the example given by me)!  If someone produces fonts which are
different but have exactly the same identifier, nothing can be done
except punishing the font developer.
