Andreas Lehmkühler commented on PDFBOX-420:
-------------------------------------------

I have two questions before I try to add your code to the trunk:

1. Your patch contains a package with 4 new classes. All of them have an old 
pdfbox license header. If I add this changes to pdfbox, we have to change the 
license to the Apache License 2.0. [1]. Is that ok for you and the author Pin 
Xue who is mentioned in 2 of these files?

2. Is the cmapSubstitutions mapping in PDFont complete or do you only add the 
mappings you are interested in? I asked, because if I add the code, I'd like to 
use a complete mapping. As far as I understand the CharCode2Unicode mapping 
there are some unicode files missing in your mapping, e.g. the korean files.
