I'm wondering whether something is wrong on our side. The fdindex contains many 
empty entries. When I tried to skip these, I got this rendering:

Lets assume that the font is correct. I fixed the bug locally that empty 
entries now get skipped in CFFParser.java, by adding {{if (bytes.length == 0) 
continue;}} after {{for (byte[] bytes : fdIndex)}}.

My first thought was that something goes wrong with the offsets because there 
is more than one fdindex entry. But I haven't been able to prove this.

I also tried to install FontForge but it doesn't show anything.

readIndexData char strings:
code 9987 len 153 at offset 298684
code 12431 len 245 at offset 301280
code 14225 len 135 at offset 303318

for code 9987 (which has this "over the top" path) I checked that position and 
length make sense, all the other bytes before/after are 0x0e, which is ENDCHAR

type2 charstring:

Lets assume that the font is correct. I fixed the bug locally that empty 
entries now get skipped in CFFParser.java, by adding {{if (bytes.length == 0) 
continue;}} after {{for (byte[] bytes : fdIndex)}}.

My first thought was that something goes wrong with the offsets because there 
is more than one fdindex entry. But I haven't been able to prove this.

I also tried to install FontForge but it doesn't show anything.

It turns out to be completely different. I ran a 2.0.1 source code build with 
the change and hit an ArrayOutofBoundsException in 
CFFCIDFont.getLocalSubrIndex(). That means we can't just skip empty entries. 
Now I get this:
 !screenshot-3.png! 
I'll investigate some more but it seems promising.
