In a thread about povr/v4.0's cmap{} code changes, Bald Eagle asked me 
if I'd dug into this issue. I'd not - though I had some guesses as to 
what might be wrong.

Well, I'm going to take a run at this issue. Due cmap{} I got some light 
exposure to several unix/linux font utilities. Plus I'll be busy with 
real life over the next couple months and this work the right sort to 
fit here and there as time allows.

I created a test case(a) to see if I could turn up some similar issues 
with linux Ubuntu shipped fonts. The first I tried in FreeMono.ttf fails 
wonderfully! Plenty of issues when Rendered in POV-Ray(povr). :-)

Aside: I can see already there are two tables in the working DejaVuSans 
not in the FreeMono. I have no idea at the moment if that affects anything.

(a) - Yep. The acute lower case i (í) was wrong.
