Thank you all the suggested tweaks, so far I am using only tweaks, what jackie_w provided in this thread (and I learned a lot from other long-time ago posting experts as well) and for me, it is a significant improvement in my kepubs.

I stayed with the -0.05 tweak between words and I am using the well-discussed hyphenation as well.

I don't have a problem with my highlights in kepub when I open them in calibre it finds all, in their place. (With the highlights I am correcting typos.)

That's good to hear

Have you looked at enough books yet to make a judgement of approximate reduction in word- and letter-spacing problems? Do you still see one-per-page? one-per-chapter? one-per-book? I do most of my reading on a 7.8" screen which probably further helps to even out word-spacing.

Really unfortunate but I do not have the quick reading ability. :-)

I just read some books with lots of dialogues and long paragraphs. Of course, the test is not complete, but earlier it was a lot of odd letter spacing problem, could be that now is even harder to notice them. I am 100% sure that your tweaks plus the hyphenation made the improvement. I am using a KOBO Clara, this is my only KOBO device (I was hesitated for an H2O but stayed with this.)

I give one example. Earlier almost all the Mr. Mrs. Ms. was oddly displayed with"spaces" around characters. Now it is very hard to notice the same.

The real visible problems are the uneven dialog spacing with the dashes (in the French and Spanish books they have the same problem). Its always in the rows which are longer than one row.

And somehow the spacing sometimes odd around "nested" tags like <i> or <b>. As I see in sigil around these remains the so-called leading spaces inside the spans.

Regarding leading spaces ... I took another look at the official KTE. I think I can send you something to try. There's a bit more to it than the previous hacks but I think it should be safe. I'll PM you in the next couple of days.

I use ^[ ] in regex search and replace in my wordprocessor to remove leading spaces, which are evil.
I then use [ ]$ to remove trailing spaces.
Optionally you can use ^$ to remove empty lines.

All referring to source documents. Calibre will export/convert to RTF which can be Wordprocessed and Save As .docx to reconvert to an ebook (MS Word or LibreOffice Writer). I do that for badly formatted ebooks rather than editing CSS.
I didn't find any better way of "export" than RTF.

I have a number of text files (.txt) that I want to import to my H2O. However, they're all contained in zip files, individually. It's simple enough to import the zips to my calibre library. When I send the zips over to my H2O, Calibre offers to convert them to a readable format, .kepub. However, the kepubs on the H2O can't display special characters like the euro and pound symbols, regardless of the font used like Kobo Mincho or Kakugo. The special characters are simply not sent through the conversion process.

But if I unzip the text files and import them as such, simple txt files, to my calibre library and send them to my H2O as txt files, the characters are perfectly readable. The problems with this are:

-the 1% txt file reading bug
-changing fonts on the txt file takes you back to the beginning of the reading material
-general lack of refinements in txt files relative to epub and kepub
-the mass operations I would have to do to unzip my files

I have the kepub output, kobo utilities, and kobotouchextended plugins - all updated to the latest versions.

Any suggestions?

Just did a quick test here and I can see both the pound and Euro symbols with most of the built in fonts for both epubs and kepubs. This is in a test book someone here created a while ago for checking just this sort of thing. That suggests it is something in the conversion from TXT to epub or kepub that calibre is doing. Check the generated files in the library to see what has been done to the characters. Or, post a snippet from the text file that includes the problems and we can have a look ourselves.

Hmmm... is the output epub file using UTF8?

in your CSS paragraph style: font-family did you declare (The font-style) typewriter, monospace?

Your body CSS is wrong; it should be "font-family: Typewriter", not "font-family: "110 %", serif, sansserif;". I'm assuming you want the font for the whole book, not just the "masina" class.

forster01 · 10-04-2019, 12:14 PM

of course i did - as i said:

forster01 · 10-04-2019, 01:35 PM

i tried all kind of patching:
No patches gives also noresult.
Un-Force user font-family i KePubs - both yes and no gives same result.
Force user font-family i KePubs - same thing no result
kepub wont recognize embedded fonts in kepub even if the font is installed on kobo.

Epub does recognize everything correctly.

forster01 · 10-04-2019, 02:18 PM

Here is sample epub - chapter 49 should be in typewriter font - only that.
