Were there any interesting stories or bugs with the PDF library?

Yes, working with PDF libraries is often accompanied by interesting stories and bugs, especially due to the complexity of the PDF format and the variety of its versions.

For example, once when using a library to generate PDFs, there was an issue with font encoding: Russian text displayed incorrectly or was completely missing. This happened because the library did not support embedded fonts or required explicit encoding specification.

Another common bug is incorrect positioning of elements when converting HTML to PDF, where CSS styles are not fully supported, and the final document looks different from what is seen in the browser.

To avoid such problems, it is important to carefully study the library documentation, test on different data, and if necessary, use alternative solutions or combine several tools to achieve the desired result.
