Include hard spaces in PDF's?

I exported a document that includes “hard” spaces (Shift+Ctrl+space) in it, but when I exported it as a PDF, they reverted back to soft spaces (that allow for line breaks.)

Do PDF’s not support hard spaces? If so, please correct this oversight.

Have you investigate about it?, we are users trying to help users.

I searched Google but can’t confirm whether or not PDF’s support hard spaces.

Hopefully, someone from Libre will see my question and follow up.

Let’s see if someone knows.
