Can I "second" this issue? I'm on the latest version and found this just now. Was hoping for any easy way to export and PDF looked to be the best option but this truncating will push me towards .html option. Which is cool too. Just like PDF option to work for code. Thanks

Just been testing this,
From my testing I found, On the current BookStack version (v0.29) that:

When using the default PDF renderer (DomPDF):

Code becomes wrapped if there are spaces in the content.
Code gets cut-off if there are no spaces and the line exceeds the page width.

When using the WKHTMLtoPDF render:

Code is wrapped if there are spaces or even if there are no spaces.

I've tried quite a few things to get it fully working via the default DomPDF render but it's tricky, it does not seem to support the word-break rule unless it's applied inline on the element, which is a level of content parsing/conversion I don't want to get into.

If you wish for better PDF output in general, I'd advise using the wkhtmltopdf render instead:
