In Adobe Acrobat Pro 2017, I am able to see an embedded font (through File -> Properties -> Font) which displays the following:
HiddenHOrzOCR (Embedded)
Type: Type 1 (CID)
Encoding: Identity-H

I am trying to un-embed the font through the Advanced Optimization tool but it won't display the font as embedded locally. This may be my own lack of knowledge but why won't the font display as an embedded font when I can see that it is embedded through the fonts display? How do I un-embed it if I can't get it to display? Thanks.
