>> Pasting the selection from https://pdf-xchange.eu/ will contain the

> Please understand this is a two-part fix:
> 1) Tweak LibreOffice pdf to write blank lines -

> ??
> 2) User must view pdf in software that captures pdf layout

> Adobe Acrobat only captures text, not layout. Maintainers of pdf viewer

> The only reason to use a pdf editor is they must capture layout to be
