Yes, that is correct. If you have a book for which that is not happening, I would be most interested in a bug report.

If I recall correctly, the main issue was not the ff, fi, etc ligatures. It were the obscure ones that almost no font has anyway.

I'll just quote some "fuzzy" comments on this thread:

On another recent MR thread but on the same topic, I found this: Quote:
I do not know of which "punctuation symbols" you were speaking. You only quoted the shy which is quite widely supported. Last edited by roger64; 04-25-2018 at 01:04 AM. |

The world of ligatures is vague. There are 'common' ones like ff, ffi, fi, etc. Then there are more unusual ones, that not always have a history in printing. One that comes to mind that was actually involved in this, was a ligature for Th.

Oh, great, I've slept since then. I vaguely remember the thread, and I remember that somewhere in time, we discussed the fact that Calibre didn't subset the shy. I think. I don't remember, I cheerfully admit, where that came to my brain. Oh, right, the bloody Edge browser. If memory serves, we'd stumbled across an issue...a client used the Edge browser to view a book. (Not intentionally; we now have to warn clients NOT to double-click the bloody ePUB, if they're running Win10, because the book will automagically open, in Edge, which doesn't always display the books to their best, to put it mildly.) Anyway, the browser used hyphenation, which we had turned OFF, per the client's instructions. The shy was displaying...either not at all, or the Edge browser was substituting its own version. That part, I don't remember. Nonetheless, my point was, obviously, Calibre didn't subset the shy, because, in our intended version, it wasn't used. That makes perfect sense. Unfortunately, what was borne home to me in that visceral way was that we don't always control whether or not that's used by the end reader--and if it's not subset, we can run into those issues, with Edge, Moonreader, etc., again. That's how I got there, to that. If I'd known that there was going to be a test, I'd have taken screenshots. ;-) Hitch |

In fact, Here are a couple of screenshots from my Kobo of a test epub. First screenshot is the in built Georgia font, which clearly has no ligatures. The second screenshot, I switched to Alegreya, which does. |

Yep. I get ligatures on my Kobo with epub2 books. (And my sideloaded fonts are all ttf fonts, so why are ligatures always called an otf feature? )

So calling something an OTF feature is not really correct (unless it has to do with the glyph outlines themselves). |

Thank you sherman for your information and examples.
So ligature display can vary according to the font (Alegreya > Georgia), the renderer (RMSDK > creengine (for koreader)), the subsetter (to be determined) and probably some other - yet- unidentified factors. The subset of a defective -on this regard- font, will not display ligatures. The subsetter has nothing to do about it. That's why it would be unfair to speak about a "bug" of the subsetter without providing an example. Examples will help us ascertain the origin of the defect. It's not a test.

It's important to note that Georgia may or may not contain ligatures in other versions. It's just that the version preloaded onto Kobo does not appear to.

Dubbs, sweetie, or my other Twoo Wuv, Tox, do you have an ePUB with Ligs I could borrow? I do NOT have one, and not to be a cranky old cow, but I really don't have the time to muck around with it. If you (or any other kindly soul) have one iwth ligs, I'd appreciate it if you'd fire it over to me to look at/test.
Use my Hightail, if you wish: Spoiler:
Thanks, and even if nobody does have one, thanks anyway... Hitch |
