Now I'm using Minion Pro (not free), but I believe it works with Droid Serif (free) too.
If I remember correctly (I don't have the reader here to try), narrow non-breaking spaces didn't work with the Gen3, and they only work with the Orizon if I enable hyphenation. It seems hyphenation triggers the use of a newer rendering engine, with better font support. When I enable hyphenation narrow non-breaking spaces (and many other kinds of spaces) are turned into question marks.
Have a look here
