Strange, I was sure that I started with this option, but you are right - it works. Thank!

Oh yes, you're using Windows ...

Yes, the replacement is now happening, but in the output file is a regular space, although I copy the non-breaking space into the command.

I have replaced all the nbsps, checked

works fine

Can you send a file after such a replacement?

[Semwize]

oops

geek1011, in places the replacement, it adds
</span><span class="koboSpan" id="kobo.9.3">
after the space

cmd when executing the command replaces the non-breaking space with the usual one. PowerShell works correctly, but when I make a .bat file with powershell launch, the launch is performed via cmd and the command is not sent correctly. In addition, kepubify with * .epub does not work in either cmd or powershell. A simple task, but now I don’t understand how to perfom it in windows.

I suspect it would be easiest to use a for loop if you want to do it file by file. Otherwise, you can just pass the directory the files are in (kepubify e:\working\epubtemp as an example).

@echo off
for %%f in (*.epub) do kepubify.exe "%%f"
pause

The above is for a batch file (the one I used is named kepubcmd). To run from a command line, change the %% to a single % and leave off the @echo off and pause lines. The "'s around the second %%f are to handle a filename with embedded spaces.

I wrote about the problem with .epub for information, of course I can process the entire directory or use the method you suggest. The main problem is that all this is done through cmd.exe, as a result, the symbol of an unbreakable space changes to a simple space. Everything works fine in PowerShell, but I do not want to use the command line, I want to click / drag the file.

Interesting. I tried converting from a Powershell prompt and from a cmd prompt (using file by file and passing the directory so 4 output files from each input file)and the SHA-256 checksums for the kepub files generated from the same epub were identical. All three test input files had multiple & #160; or & nbsp; embedded. I also tried dropping a single file and a directory on kepubify and it converted the file/directory as expected with the identical SHA-256 checksums as any other method I tried.

BTW, IMNSHO, when you write about a problem, including an image of a method that will not work is not the best way to demonstrate the issue.

Given that I do not see the problem of a non-breaking space being converted to a space, perhaps you might want to look at the locale settings on your computer.

Here is the book file.
Диккенс Чарльз - .epub
It contains non-breaking spaces:

After conversion, they are replaced by & # 160;
I managed to leave them in their original form only with the help of the command in powershell. Maybe there really is a problem in the system settings, I don’t know.
P.S. The presence of characters & # 160; in the text leads to the following result:

Perhaps you might want to check the following post (or the entire thread it comes from). The renderer used by Kobo for kepubs has some issues with non-breaking spaces. See GeoffR's post ( GeoffR post 5 ) or the entire thread at KEPUB and non-breaking space for more information.

I did some testing with a file which has numerous non-breaking spaces and after conversion to kepub, it didn't matter if I had the character or numeric entity as far as how the display looked.

I'll double check this with the book you attached but suspect I will see the same behaviour.

Edit: I looked at the epub file you attached. The non-breaking space used was the numeric (#160) form despite no Kobo spans or other evidence that it had been converted to kepub. I did a quick bulk replace in Sigil and tried a kepub conversion. The & nbsp entities were all converted back to numeric entities so I edited them back to & nbsp. I've attached that file here though the kepub seems to have been shrunk to k.

One other item is that before and after conversion, the file made both Flightcrew and epubcheck very unhappy. You might to check and fix those errors—garbage in, garbage out comes to mind. fb2mobi.py does not seem to do a very good job of generating epub code.

I stopped understanding the conversation, I'm sorry.
The file I attached contains non-breaking spaces.

After kepubify, it looks like this:

I do not need it, I need it to remain as in the first screenshot. With the help of changes respected geek1011 I do this, in powershell.
In cmd.exe after executing the command (no space after &):

kepubify-windows-64bit_2_3_1_2.exe --replace "& #160;|*"

Replacement occurs, but the space is normal, not a non-breaking space. In Windows, batch files are processed via cmd.exe, so I cannot automate the replacement process.

Thanks for the info, this is not a problem for me now.

The epub you attached is filled with non-breaking spaces. Sadly, they are the numeric entity form (#160) and not the character entity form (nbsp form. Depending on the editor you are using, these may get converted to nbsp form when saving. In Sigil, this is the preserve entities preferences area.

Have you checked on the issues with non-breaking spaces in Kobo epub files as described in the thread I linked to?

Not worrying about errors in your epub? If you have errors, it is hard to say if one of those errors is the not cause of your issues.

When I was playing with Konstantius's ebook, I noticed one oddity in the converted kepubs when the end of lines were disappearing. The original code from my test file read:

<?xml version="1.0" encoding="utf-8"?>

  "http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd">

While after conversion to kepub:
