I've got a PDF document I've imported into Inkscape as a raster image with poppler/cairo import. The document has text and mathematical equations and I want to copy parts of it into a another Inkscape document. When I try to select some text and copy it into it, it seemingly changes font, size and adds lots of spaces between the letters.
How do I copy this without it changing? If I import internal import or the vector alternative, the text and mathethematics loses it's formatting/font which I want it to retain.
