KoReader - fonts

BobC · 12-31-2018, 12:58 PM

I have KoReader (2018- 12) running on a Kobo Glo. When displaying an EPUB document which has paragraphs declared as :

font-family : serif
font-family : sans-serif
and
font-family : monospace

I'm getting confusing results.

I have embedded fonts turned ON, the document does not have any fonts embedded in it - I am relying on the above generic font declarations.

The document displays correctly on other EPUB readers but in KoReader both the serif and sans-serif paragraphs display using the font selected in KoReader's menu. However the monospace paragraph displays in monospace irrespective of the menu selection.

Effectively this means that it's all or nothing for san-serif either the whole document (apart from monospace) is in serif or sans-serif.

If it wasn't for the monospace stuff displaying correctly I would think that KoReader didn't respect font-families within the EPUB, however it does handle that case.

Is this a known issue or a design decision ?

If the san-serif typo stems from your original file, that might be the problem?

Well spotted - however it is just a typo in the posting; it's sans-serif in the css file.

It's as if the font selected in KOReader's settings is overriding that in the css EXCEPT when it's monospace.

@poire-z helpfully reminded us of when we last discussed this: https://github.com/koreader/crengine/pull/216

TL;DR: Yes, there's no distinction between the sans & sans-serif generic names, by design. If you need one, embed fonts, and refer to those families explicitly.

Thanks for the helpful explanation. I find that I don't need to actually embed the font, simply change the css from

Code:

font-family : sans-serif;

to

Code:

font-family : FreeSans , sans-serif;

As the FreeSans font appears to be installed with KOReader.
