I've seen it, but I hate putting font handling in a PDF library... if there's any way to upstream it to allsorts, that would be better. |

Hi, I have implemented support for OTF fonts in CFF format (CIDFontType0) with partial success.
The generated PDFs render correctly in Adobe Acrobat, Safari, and Preview.app (Mac), but they do not display properly in Chrome, Firefox, or PDF.js-based tools. I suspect the issue stems from how the custom CMap resource is written, though my understanding could be completely off.
Another issue is that the process is very slow, likely because it reads large tables multiple times.
Additionally, I have updated the subset font to include glyph ID
0, as per the allsorts documentation.Please take a look and share your opinion.
Thanks!
