Hello, and thanks for your error report!

I will probably find time to fix this within the next view hours (it should be relatively trivial, assuming the error is caused by what I think it is caused); I'll inform you once the bug is fixed.

I can't replicate the problem on my own machine, probably due to using a different operating system, but I found two possible ways to fix it, one which is more elegant (though I'm not sure whether it actually works due to being unable to test it), and one that I am entirely sure will work. Both will make no difference to you as a user.

Could you update to version v1.17.3 (e.g. via pip3 install --upgrade gh-md-to-html==1.17.3) and tell me whether it fixes the problem?
In case it doesn't, you can update to v1.17.4, which should certainly fix the problem.

You need to specify the positional arguments before the optional ones, like this: C:\ti-software\cv>c:\python38\python.exe -m gh_md_to_html readme.md -o OFFLINE -p cv.pdf

It seems likely to me that this error always occurs when you run the tool for the second time in a row after installing it, no matter whether you use the online or offline version.

with 1.17.4 the offline version gives the error:

Are you sure you have wkhtmltopdf installed like the documentation sais?

Probably the thing I mentioned above.


It seems to me that 1.17.3 and 1.17.4 seem to have the same underlying issues, so I based 1.17.5 on 1.17.3.
Would you mind updating and re-checking again, this time with the arguments in the specified order? I didn't do anything about the error regarding wkhtmltopdf for now, though, since I suspect it is because of missing dependencies (could you verify whether you have wkhtmltopdf installed?)

You might encounter some more UnicodeEncodeErrors in different places after this update. If this is the case, I can fix them, but I want to see whether there are any first so I don't add additional clutter to fix a problem that doesn't exist.

wkhtmltopdf was installed, but it did not add itself to the PATH. After
set PATH=%PATH%;c:/program files/wkhtmltopdf/bin

I finally got

So, that works! Two problems with the pdf: an image was not included, and the single-pixel-border tables were now all double-bordered. But: it is a multi-page pdf, which I didn't get with some other conversion I tried.

But the online version still errors:

Glad to hear that, I added a note to the README that you have to add wkhtmltopdf to the PATH on Windows.

an image was not included, and the single-pixel-border tables were now all double-bordered.

Looking into this right now.

But the online version still errors:

That's weird; also looking into this right now.

So, that works! Two problems with the pdf: an image was not included, and the single-pixel-border tables were now all double-bordered.
But the online version still errors:

The issue with the double border was actually already resolved in a much older version, now that I think about it, so I'm surprised this is happening to you. On my system, I can replicate neither the error with the online version, nor the missing image, nor the error in the online version.

Some reasons why this might be occurring for you:

  • Are you sure the missing image and double borders are in the resulting PDF file, or do they only occur in the generated HTML file? In case you tried to open the resulting HTML file in the browser (e.g. by double-clicking it) and expected it to show the image and use GitHub's README stylesheet, you should have added the -w . option. The reason for this is that gh-md-to-html (by default) uses absolute relative links for embedding CSS and images, based on the assumption that you want to host the generated HTML file at the root of a website. If you want to be able to view the HTML file in the browser on your local machine (with file://), you need to supply the -w . option.
    This shouldn't affect the resulting PDF file regardless, though.
  • Are you sure you are using the latest version of wkhtmltopdf (version 0.12.6), to which the README links? Older versions can have issues with images and style sheets, which is also why the README specifically links to the newer version, though I admit I should have made it clearer that there are explicit version requirements for wkhtmltopdf in the README.

Here is the PDF I get with both commands you used:

cv.pdf

Would you mind sharing your own result for comparison? You can drag-and-drop it into GitHub's text box to attach it to your reply.

using -w . both the offline and the online version gives the correct html (single bordered tables, with image) but the wrong pdf (double bordered tables, no image).

I assume that with "still open", you mean that it is opened in the PDF viewer, right? Because that's probably because the PDF viewer locks the file as long as it is opened and blocks write access in the process, leading to a failed write (this seems to be the case with Acrobat Reader, for example). There's nothing gh-md-to-htmlcan change about that, though, because there is no way to prevent or circumvent other programs from blocking write access to a file.

It's useful to know nonetheless, though, since I could add a more helpful error message for that. Thanks!

using -w . both the offline and the online version gives the correct html (single bordered tables, with image) but the wrong pdf (double bordered tables, no image).

I'm currently looking into this (can't replicate it, though; probably has to do with the different file paths that Windows and Linux use).
Thanks for sharing the files!
