Characters not appearing on PDF export

I have a list in a document made with bullet points that are crosses (Using the LibrrOffice bullet list) When I try to export pages from the document into PDF they do not transport. If I export the whole document they appear as I want them. Is there any way to make this happen when transporting a selection of pages? What I get is a box for drawing them in in LibreOffice Draw.

(I think what I may need is a way to embed a section of a document into a PDF)

I can’t confirm described behaviour. I created a document of 2 pages and exported single 2nd page to pdf document. Crosses (list) remained as crosses.

Can you explain the proceeding in more steps?

IMO only pages or selections can be exported; you may select an entire section and then export - but page breaks won’t be exported the way the given lay-out of the original Writer page is visible…
