All epub reading software knows how to de-obfuscate the fonts. There's no need to do it manually.
Remember that the fonts will only have been licenced for use in that ePub, so using them elsewhere will be piracy, unless they've been released to the public by the creator, in which case you'll be able to easily find a non-obfuscated version online. |

Seriously - ePub Font obfuscation is a standard (well, two actually - Adobe's and the IDPF's). Any PC-based ePub reading program will automatically handled obfuscated fonts. If you've tried it and it doesn't work, the ePub isn't using standard obfuscation, and so there won't be any tools to help. Not that there are likely to be such tools readily available for obvious reasons. Last edited by pdurrant; 07-10-2019 at 09:14 AM. |

ALAS, inside the mobi were simply "font001, font002," etc. I couldn't even be sure which was which. I tried to view the font001, etc., files, but, more alas, I couldn't do so. I had to infer the name of the font from the CSS, and of course, anybody could name any font anything, in their own CSS. Amazon uses their own obfuscation as well, and I suspect that the font was subset and encrypted in INDD, before being exported to ePUB from whence the MOBI was made (as it's a Random House book). So, I was triple-screwed, dang it. I wish there were a way to de-encrypt and display fonts, for those times when I decide I just "gotta have that," (and thus need the name), but the truth is, if that existed, people would abuse the holy hell out of it and steal fonts. No point in arguing it, we all know it's true. Sad--but true. Hitch |

FWIW, Font obfuscation (both major) types are tied to the main BookID uuid of the epub. So they are worthless in obfuscated form unless you have the BooKID of the exact epub they are used in.

https://www.myfonts.com/WhatTheFont/ I'd be interested in knowing what the font is if you find out. |

So...I started tracking it down and when I, er...unpacked the mobi, I found the NAME of the font. but only part of it. I then bought a Kobo version, (due to all the brain-damage that Nook has caused in trying to move files from A o B) and anyway, I found the NAME of the font, but it still seems to not exist. Anywhere. Historically, now...noplace. Either the layout person created it him/herself, or, it's one of those fonts from those old font CDs, way back, you remember those? For crafters and the like? That's why I was asking about the initials/acronym/? around the font name. ETA: Wolfie: PMed you. Thanks, Hitch Last edited by Hitch; 07-23-2019 at 12:51 AM. Reason: PM'ed Wolfie |

I did try What the Font and got noplace. But with What the Font, you can submit your entry for actually people to have a look at it and try to figure it out. So I've gone that route. I hope it works. |

This may be a complete red herring but I'll say it anyway...
When I occasionally extract fonts from a PDF I see names like: Code:
KIIFHM+AGaramondPro-Regular-1982.cff MIHLFK+FreestyleScriptLT-1421.ttf FPHLHJ+Able-1157.ttf |

I can't remember where but a few days ago I was reading about how the Bitstream 500 fonts cd has some nice fonts on it. I still have a plastic drawer thing for cds and it was in there. All of the font file names are TTnnnnnM_.ttf where the lower case ns are digits.
Is there any program that will print a 1 line sample for each font file, multiple samples per page, and I could generate samples and maybe generate a pdf. |

Heh, the disc was readable, and my cd/dvd drive (whatever it is) also still works. The disc is surely older than Hitch's ancient Kindle.
Not the full alphabet but perhaps enough to give you an idea: bitstream_500_fonts.zip |
