> I can see that there is a confusion in the process between GID and CID values. The reason may not be entirely clear to me, but PDCIDFontType2Embedder.buildWidths(COSDictionary cidFont) seems to name "cid" something that in my opinion is still a glyph id. And when it comes to PDCIDFont.getWidth(int), the "widths" map that should presumably contain cid->width values in reality contains git->width.
