Forma I will use whatever the default font face is set for a book. Here's why. - Page 4

It's a configuration file setting not a patch.

If you already have a [FeatureSettings] block, just add the Screenshots under it, otherwise adding both (false disables, true enables). With a sleep cover, I just leave it at true.

[FeatureSettings]
Screenshots=false/true

Thanks for sharing.

It would be great if there's an easy way for Calibre automatically go through our library and determine which books have fonts that are used in only one (or 2 or 3) pages, and then strip the books of those fonts, to save on space.

I like that you have a choice. I can't read the publisher's font. Spacing is always too close. My Mom has no problem with it. She read the publisher's font if it is downloaded from Amazon, but otherwise a font that shows the italics nicely in the sideloads.

You are right! In Calibre, I "exploded" the book, and then went to the fonts folder. I see an EBGaramond family: bold, italic, bolditalic, regular.

This folder is 2.9 MB large. Yikes!

Following is the html from an example of that very page that's in the many Penguin/Random House ebooks. If displaying this here is inappropriate, let me know and I'll delete it.

Shift Light is the font. In a lot of cases, though not all, calibre indicates that the embedded Shift family fonts are invalid.

Dear Mirage,
As thread-creator, I welcome your post and wouldn't want it deleted.

Constantia is the one I use about 97% of the time (on all brands of eReaders) and it's pretty dark and clear "as is" on all of them. The built-in Georgia on the Nook Glowlight Plus (2015 version) is comparable when using the "thicker" setting.

Most of the built-in fonts are too light (not enough contrast) for me. Probably an issue with my eyes.

Actually, it's easier to install NickelMenu as you can have an option for toggling screenshots. I have NM installed and I like being able to take screenshots without having to pug in the H2O, edit the config file, take what screen shots I want, plug the H2O in again and edit the config file again to remove screen shots. It's so much easier.

Another feature I really like is the USB feature. It allows me to plug the H2O into the computer and then eject it. I can then get the H2O to ask if I want to connect or not without having to pull the USB cable. It's great for when you want to connect to Calibre a second time to update the series and description.

There is a lot more the NM can do such as allow you to choose if you want to go to the home screen or my books from te book you are currently reading.

If the spacing is too close, use the line height slider from the Aa menu to increase the spacing. Problem solved.

How do you find Georgia on Kobo?

Is it complaining that the font family is invalid or is it complaining about their listing in the content.opf file. As an example, you see the font listed with "application/x-font-ttf" while an epub3 wants "font/ttf" See RFC-8081 for a list of the font top level type and subtypes.

Another example would be:

Code:

<item id="seraphine-regular-otf" href="Fonts/Seraphine-Regular.otf" media-type="application/vnd.ms-opentype"/>

<item id="seraphine-regular-otf" href="Fonts/Seraphine-Regular.otf" media-type="font/otf"/>

<item id="seraphine-regular-otf" href="Fonts/Seraphine-Regular.otf" media-type="font/otf"/>

I can't definitively answer the question because I don't know enough about the specifics of the epub specs to say, though I've done my share of tweaking of them and have done plenty of html/css work. In other words, the innards of an epub file are familiar to me, but I'm not fully versed in knowing what to make of everything I see there. I'm not looking for any help on this, FWIW. I was just providing the code for the page @JSWolf provided above because I've seen it so many times in the Epub editor in calibre and figured it might be of interest here. That said...

There is a red icon with an exclamation point within it to the left of the offending font name in the Fonts section of the file browser in calibre. Hovering over the icon or font name invokes a tool tip that reads "Not a valid font." This is for Shift-BoldItalic.otf and Shift-Light.otf. I'm pretty sure that the only place this font is used is in the code for the page that @JSWolf provided a screen shot for. That's how it's been when I've searched for it in books to see if deleting the font would potentially create any problems with using the publisher's choice, which I tend not to do, anyway. The @font-face descriptor is always in the <style> tag in the header of the html file for this particular page. It's not in any of the css files.

Here's what the opf file contains for an invalid example of this:

Code:

<item href="fonts/Shift-BoldItalic.otf" id="Shift-BoldItalic.otf" media-type="application/vnd.ms-opentype"/>
<item href="fonts/Shift-Light.otf" id="Shift-Light.otf" media-type="application/vnd.ms-opentype"/>

I don't know, I only use it on the Nook Glowlight Plus (2015) because it's built in and I can't side-load my Constantia font to it.

I run every single one of my books through a Calibre conversion where I strip the font property :-D.
