kepub hyphenation: only when justified, often incorrect...

So it differes from epub to kepub...

I found the solution.

So, I just want to thank you a thousand times.

My kobo is back in business on 1.9.17 with my sideloaded epubs and none of that hyphenation ridiculousness!!!

It also differs depending on what font you are using (seriously) and the size of the font.

The book I tested on is a drm free ePUB of In the Garden of Beasts by Eric Larson. I tested with a right ragged edge. Someone else might want to test justified text.

I used the same size font throughout, a small for me, medium for younger eyes. It was 7 ticks to the right on the size slider.

Georgia, Chapter 1, first page: 4 hyphens
Georgia, Chapter 1, next page: 10 hyphens

Delima, Chapter 1, first page: 1 hyphen
Delima, Chapter 1, next page: 5 hyphens

Amasis, Chapter 1, first page: 6 hyphens
Amasis, Chapter 1, next page: 1 hyphens

Then I went 2 clicks larger. You would expect fewer hyphens as there are fewer lines. But since more hyphens per page seems to translate into less reading pleasure, I thought it was worth seeing this.

Georgia, Chapter 1, first page: 2 hyphens
Georgia, Chapter 1, next page: 1 hyphens

Delima, Chapter 1, first page: 2 hyphen
Delima, Chapter 1, next page: 0 hyphens

Amasis, Chapter 1, first page: 8 hyphens
Amasis, Chapter 1, next page: 1 hyphens

The results vary enough that it might explain why the hyphenation drives some folks crazy and doesn't seem to matter much to other people. Also note that Amasis actually went up when the text got larger--I don't necessarily think it means much. A larger test would tell us more.

What is the biggie to me is that font choice and size do matter and playing with fonts might be worth doing until the fix comes down if you are going to read ePUBs.

But that's only the amount of hyphens, not wether they are correct or not, right? Of course there may be 0 hyphens on one page - may happen with kepub or epub...

BTW German hyphenation is even worse than English... something like "v-or" which would be t-he same i-f I would hyphenate English words with one syllable - it should never happen.

You had already established that the hyphenation was correct in ePUBs. They looked that way to me, too.

For kepubs, I use ragged right and it's all good . I was only looking at the number of hyphens in ePUBS. I wasn't taking away from anything you said, Jaden, I was expanding on it and suggesting that people reading ePUBS might want to figure out what font and font size worked best for them in terms of the annoyance of the hyphens.

I just wanted to make sure we where talking about the same thing - that different font/fontsizes may result in less hyphenation throughout the book, but unlikely in no hyphenation.

I do the same for kepubs - actually for epubs, too, only that it doesn't matter in case of hyphenations.

At least the English hyphenation in epubs is correct - the German isn't, not at all.

Also experimenting doesn't always help - might be that 3 pages are nice and (almost) clean and the next 3 might have a lot of hyphens. At least that's what I experience. Not saying that there might be no cases where a different font/fontsize eliminates almost all of the hyphens...

Yup. The fact that in one case Delima had 0 hyphens on one page or that Georgia had 10 hyphens on one page doesn't mean anything. That the number of hyphens seems to be influenced by font choice and size might explain why some people are really bothered and some people are not.

Since I did a reset of 2.0 (wanted to have the same number people are getting now), I've been using Delima. The hyphen issue really hasn't bothered me. The size I use is the one I tested on in the second batch. It works for me .

Looking in the hyphenation dictionaries:

DE: LEFTHYPHEMIN 1
      RIGHTHYPHEMIN 1

EN: LEFTHYPHEMIN 2
      RIGHTHYPHEMIN 3

ES: LEFTHYPHEMIN 1
      RIGHTHYPHEMIN 1

FR: LEFTHYPHEMIN 1
      RIGHTHYPHEMIN 1

IT: LEFTHYPHEMIN 1
      RIGHTHYPHEMIN 1

PT: LEFTHYPHEMIN 1
      RIGHTHYPHEMIN 1

So all but english can leave one letter followed by (or preceded by) a hyphen!

[taming]

I wonder if they bought/got the hyphenation dictionaries and didn't recognize that it came without any customization. I'm betting this is easy to fix. The fact that kepubs break in the wrong place, maybe not.

I think it depends on a lot of things like the book itself, the font and the fontsize etc.

But yes, that explain it. Some people might get hyphens that rarely (and might only have correct hyphens) and are therefore not bothered by them - or maybe haven't even realized there are hyphens at all.

By now I have changed the German hyphen.dic (with help of a file provided by WS64) in a way that I don't have any hyphens at all (60 characters before the hyphen, 4 after - words that long are unlikely going to be in my books ).

And it seems to me that page turns are faster now that there's no hyphenation. Could be my imagination, though...

I am sure there is some sort of algorithm that factors in line length, frequency of words of a given length , and hyphenation rules that explains everything .

[Jaden]

If you manipulate the English and German hyphen.dic there are no hyphens anymore. Except for very, very long words (which are also very unusual).

LEFTHYPHEMIN 60 RIGHTHYPHEMIN 60 for example eliminates all hyphenation.

@Jaden: see this post of mine where I describe those values https://www.mobileread.com/forums/sho...&postcount=516

[murg]

I remember seeing a post or a release note that the English hyphenation dictionary originally had values of 1 and 1, and was changed to 2 and 3.

Obviously, someone at Kobo didn't make the same change for the non-English dictionaries.
