Hi! Thanks for this bug report. I’ve tried to render the HTML sample you’ve given, but I can’t reproduce this bug. Here’s some Python code that should correspond to your issue: from weasyprint import HTML
HTML(string='<h3 style="display: inline-block;"> Some title\u2028</h3>').write_pdf()Does it crash for you? |
|
Hello |
I’ve tried to use your HTML, but it doesn’t crash for me. Could you please share a HTML file (instead of pasting it in a comment)? |
|
You find attached the html file (inside the zip file)
|
|
It’s now fixed and tested! |

Version 59.0 ------------ Released on 2023-05-11. This version also includes the changes from unstable b1 version listed below. Bug fixes: * `#1864 <https://github.com/Kozea/WeasyPrint/issues/1864>`_: Handle overflow for svg and symbol tags in SVG images * `#1867 <https://github.com/Kozea/WeasyPrint/pull/1867>`_: Remove duplicate compression of attachments * `d0ad5c1 <https://github.com/Kozea/WeasyPrint/commit/d0ad5c1>`_: Override use tag children instead of drawing their references * `93df1a5 <https://github.com/Kozea/WeasyPrint/commit/93df1a5>`_: Don’t resize the same image twice when the --dpi option is set * `#1874 <https://github.com/Kozea/WeasyPrint/pull/1874>`_: Drawn underline and overline behind text Version 59.0b1 -------------- Released on 2023-04-14. **This version is experimental, don't use it in production. If you find bugs, please report them!** Command-line API: * The ``--optimize-size`` option and its short equivalent ``-O`` have been deprecated. To activate or deactivate different size optimizations, you can now use: * ``--uncompressed-pdf``, * ``--optimize-images``, * ``--full-fonts``, * ``--hinting``, * ``--dpi <resolution>``, and * ``--jpeg-quality <quality>``. * A new ``--cache-folder <folder>`` option has been added to store temporary data in the given folder on the disk instead of keeping them in memory. Python API: * Global rendering options are now given in ``**options`` instead of dedicated parameters, with slightly different names. It means that the signature of the ``HTML.render()``, ``HTML.write_pdf()`` and ``Document.write_pdf()`` has changed. Here are the steps to port your Python code to v59.0: 1. Use named parameters for these functions, not positioned parameters. 2. Rename some the parameters: * ``image_cache`` becomes ``cache`` (see below), * ``identifier`` becomes ``pdf_identifier``, * ``variant`` becomes ``pdf_variant``, * ``version`` becomes ``pdf_version``, * ``forms`` becomes ``pdf_forms``. * The ``optimize_size`` parameter of ``HTML.render()``, ``HTML.write_pdf()`` and ``Document()`` has been removed and will be ignored. You can now use the ``uncompressed_pdf``, ``full_fonts``, ``hinting``, ``dpi`` and ``jpeg_quality`` parameters that are included in ``**options``. * The ``cache`` parameter can be included in ``**options`` to replace ``image_cache``. If it is a dictionary, this dictionary will be used to store temporary data in memory, and can be even shared between multiple documents. If it’s a folder Path or string, WeasyPrint stores temporary data in the given temporary folder on disk instead of keeping them in memory.

I have an html element in my document which contains the following:
<h3 style="display: inline-block;"> Some title </h3>the special character at the end of the title is LS, a Line separator character (~ \u2028)
I got the stack trace of the error that you find right bellow.
And after digging inside
inlines.pythe functionsplit_text_boxis not able to get the right text from the element. At a point it is able to encode it to UTF-8 which result in this string:b' Some title\xe2\x80\xa8 ', but not to complete the parsing.I was able to overcome the issue by setting
style="display: block;". So somehow the line break from the display block is preventing that character from being rendered. But I have many element with inline style.Is there a way to fix this without changing the styling of my entire HTML document? something like escaping Unicode non printable characters?
the WeasyPrint version that I have is 52.5. I tried with v57.1 and I got the same issue.
The text was updated successfully, but these errors were encountered:
