Description

The Morisawa ShinGo Pro R font cannot be embedded into PDF document.

How to repeat
1. Get FOP from trunk@1786161
2. Get Font from https://github.com/skyavy-cebu/DoubleClick/blob/master/web/fonts/A-OTF-ShinGoPro-Regular.otf?raw=true
3. Use my config file and generate the PDF, there is no error reported.
4. Open the PDF file in Acro-Reader, it will report the "cannot extract the embedded font" error.

Notes:
I can display normally with full embedding.
(Please refer to test.fo, test_subset.pdf, test_full.pdf)
When examining the subset font with CFFParser, the following Exception occurred.
