Description
A client sent in a set of PDFs that had embedded font programs but the font engine could not correctly display the glyphs. The glyphs where asian and the font was a CID font with with CIDtoGID that wasn't the standard identity mapping. The font engine and the respective Cmap is incorrectly initialized making it impossible to correctly map a none identity cmap.
For example consider the cid's below, the current algorithm that organizes and compresses the CID -> GID makes it imposible to retreive the GID value for a given CID because CID and GID are not equal.
CID GID
0x0704 = 1796 14
0x0db3 = 3507 24
0x08ba = 2234 5
ox0d15 = 3349 53

Quite a bit of work was done to address the cid to gid mapping error. QA passed and there are quite a few other documents that had the same problem that now render correctly.
Marking as resolved.

After a round a QA there where a few remaining issues around how StringObject handle there 2 and 4 bytes cids. Pretty sure I've go this all straightened out for now but will do one more round of qa to be sure.
