Font decoding options for born-digital PDFs:
Computational effort increases from top to bottom, as does the level of scrutiny the embedded fonts are subjected to. "Decode Unmapped" usually is a good starting point, with the option to escalate to "Verify Mapped" or "Decode All Glyphs" and re-convert a PDF in case the conversion result has too many character errors with "Decode Unmapped". "Render Glyphs Only", and especially "Do Not Decode Fonts", a quick decode options useful mostly for testing some PDF, or for extracting figure images and graphics with little regard for the text, even though the former can (and often does) produce good results for PDFs whose embedded fonts come with faithful and complete Unicode mappings. If the latter is known to be the case, "Render Glyphs Only" is a viable option.
@gsautter can you please explain all the options to encounter in the opening menu of GGI and what when should be used so we can add this to the manual.![image](https://user-images.githubusercontent.com/4609956/70085674-03aac600-1611-11ea-8455-3a80b51fdae4.png)
