We're creating PDF files using FDF format. Unfortunately, when it comes to displaying characters like © (©), ® (®); and ™ (™) they are simply rendering as © rather than the proper symbol they represent.
Is there a way to tell the FDF to render this properly?
HTML centric jargon, the &[something], is the problem. Each character of a "&[something] has a defined value that maps to Unicode. That is what PDF works with (Ref. ISO 32000-1).
Try using the actual ANSI number for the characters. Again, PDF is not HTML.
ANSI 0169 for ©
ANSI 0174 for ®
ANSI 0153 for ™
