Firmware 3.16.0 Discussion

The KEPUB and EPUB readers use the same hyphenation dictionaries, but they use different hyphenation algorithms, so the results are not exactly the same. The KEPUB hyphenation has improved in firmware 3.16.0, but the EPUB hyphenation is still a lot better.

I use text alignment left, in epub that never causes hyphenation or it is so good that I never seen it, in kepub it is always wrong, until 3.16 it is been cut off at places where it never supposed to be, in 3.16 it cut's off while there is still enough room to cut it off further,or it cut's off while there are only 2 or 3 characters left so in that case it looks a lot better to transfer the whole word to the next line,and very overdone/overreacted fills the right side of the book full with hyphenated words..
Language is set on Dutch and in all the times I edit my books I have never seen any restriction for hyphenation in the stylesheet.
I edit my books most of the time because I hate the text ident at every new alinea and the "stredged" lines so text alignment is set to left where it is centered.
I also cut off any page margins where they are not needed.
(It is the same when you buy a hardcover book while the text on the page fit on a paperback, leaving one inch white on all sides of a page...)
To much books are all so hard coded in the css to look like the paper format,overrruling all the sliders you have on the reader to do it yourself..
I don't know if there is a hyphenation dictionary for Dutch language is included in the Kobo firmwares.

@Nick_1964 : a great way to achieve correct hyphenation in epub or kepub (which I used before 3.16 but is now correct in french and in english, for I can see of it) is to use kobo_extra.css at the root of your kobo device, with :

body {adobe-hyphenate: explicit !important;} /*epub*/

body { -webkit-hyphens: manual; } /*kepub*/

checking ‘modify css’ in kobotouch or kobotouchextended plugin and hyphenating the book manually using the 'hyphenate this’ calibre plugin with the dutch hyphenation dictionary of openoffice.org installed inside. This way, the hyphen algorithm of the kobo is not use at all, but you will get correct hyphen for all your books.


You can also install the dutch dict in your kobo (and trying to use the hyphen algo of your kobo) by using two alternative methods (the KoboRoot.tgz update or frostschutz method).

There is an hyphen dict is included in the kobo firmware, named hyph_nl.dic, check the <dc:language>nl</dc:language> tag included in the book’s content.opf to see if the language code is correct.

That explains why you have never seen it. I tend to forget that some prefer to read that way.

Yep, I like my books left aligned,no ident, no margins, no set linehight, no preferred size of font and no font set,new chapter start at a new page.
I have all this beautiful sliders to set it the way I like it and the designers overrule all this, what can I do with my favorite fonts when the designer want me to read it in his font which he includes in every book.
Most readers are perfect capable to leave this to the user.
Some books need it, they have beautiful starting chapter letters like a monk calligraphed it by itself, then it really adds something but for the rest of it, I want full control !

Thank you for your beautiful suggestions, I will look forward to it,but for now I rather like it without hyphenation, I will unzip the dictionary's to inspect them.
If it saves space,it is useful but to do it ,for example at a 12 letter word and put the - after 2 letters at the end,it make it not really look better, expecially if the line also ends with that word,then only the part behind the - will fill that line and leave the rest empty.. then it adds nothing to the reading experience.

Is anyone on 3.16.0 in the UK?

Bought mine 2 weeks ago and it's still on 3.15

Plug it in to USB and look at the .kobo/affiliate.conf text file

Mine said "affiliate=Kobo" and would not update. I changed it to "affiliate=bestbuyca" and then hit Sync and it immediately downloaded the update and asked if I wanted to update now. You can revert the affiliate line after the update if you want.

For example it will hyphenate everywhere as ev-reywhere even when there is no leading punctuation and I have LEFTHYPHENMIN set to 3.

(Still a big improvement on earlier firmware though, at least the hyphens are always at valid positions now, and I'd rather have too much hyphenation than too little.)

I have discovered that the KEPUB reader is in fact reading the LEFTHYPHENMIN and RIGHTHYPHENMIN values from the hyphenation dictionary, but it seems to be miscalculating their value by one.

For example, the English hyphenation dictionary comes with LEFTHYPHENMIN and RIGHTHYPHENMIN values both set to 5, but the KEPUB reader reads the them as 4. When I change to my preferred values of 3 it reads them as 2.

So if you only read kepubs and are familiar with installing new hyphenation dictionaries then you can work around this problem just by adding one to your preferred value. But if you switch between reading epubs and kepubs then it is a bit of a pain because both readers use the same hyphenation dictionary.

(Edit: It might be a bit harsh to call it a miscalculation, it could be a difference in interpretation with the Adobe RMSDK reader over what the values represent. But that is still a problem because it makes it impossible to get consistent hyphenation when switching between reading kepubs and epubs.)

What languages do both of you read in? It's quite possible you don't have a hyphenation dictionary for ePub/RMDSK in the language you read.

As for up/downgrading, you don't always need to do a factory reset. It would depend if you need to go back to an older uboot.

I don't care too much about hyphenation to be honest, full justified as long as gaps are not outrageous is fine with me.

That is smart. I will take note. I must admit I am very tempted to put 3.16 on my H2O. I guess there are hidden folders to copy as well?

Unless the CSS is set to not allow hyphenation. That could be doing it. I've seen that too any times.

Depends on the PC you do it from. Under Windows, they aren't hidden. On a Mac or Linux machine, they will be hidden.

Kobo Aura HD, 3.16, Calibre/sideloaded kepub.

I have noticed something which I first thought just was imagination or that I did something wrong.

What happens is that I touch the area on the screen to go forward one page, but end up several pages earlier! (Maybe around 5-6 pages or so.)

Trying to remember when och how it happened, I'm sort of guessing that it may be that the reading of the page has taken longer than usual, pressing "next page" and nothing happens, and then again it goes back several pages. But I'm not really sure....

If/when it happens again I will try to think about more details.

Anyone else seeing something like this?

[Ripplinger]

I'm pretty sure the Aura HD uses infrared beams so there's a very slight gap between the bezel and the screen for the beams to operate. Try blowing canned air around under the bezel where it meets the screen, or gently use a soft-bristled brush to clean under there. It could be a piece of dust or small particle of something that got stuck under the bezel in that tiny gap.

[patrik]

Hmm, I usually keep the reader very clean (dislike fingerprints...) but due to travels it has been neglected for a while and it did have much more "dust/dirt" along the insides than usual. It's now clean and nice. Will be interesting to see if I get none of the non-responiveness and strange back-jumps.

Thanks! :-)

Installed 3.16 on my mini with several patches. Running fine with kepub - epub not tested.

Wow! I guess I'm not going nuts after all. I see similar behaviour. It doesn't happen often but it does happen. Possibly when I wake up the Glo HD from sleep but it seems to happen mostly when I tap in the upper right corner. No rhyme or reason to it though.
