I have a pdf file includes a opentype font "SourceHanSans" what is generated by JasperReport 6.3.1 + iText 2.1.7. The pdf can been viewed by other pdf reader such as chrome pdf reader. But the Adobe Acrobat Reader DC prompt an error and it cannot display the font correctly.
I found the Adobe was fixed the similar problem in past. Did the patch apply to the latest version?
