Tilman Hausherr commented on PDFBOX-2091:
-----------------------------------------

I looked in the spec, it is described on page 430 in the 1.7 spec. The text is 
inconclusive to me. The thing that irritates me is that the branch of your 
change is for not-symbol fonts, yet it opens a symbol table. Per that spec, we 
should look in the Mac table. However the spec tells that "Some popular 
TrueType font programs contain incorrect encoding information. Implementations 
of TrueType font interpreters have evolved heuristics for dealing with such 
problems".

I have made your change in my version and let it run on more files to see what 
happens (and will try different flavours of the fix), and to see how often that 
part is used.

> In this case it is "yaccute".
