PDF file format allows to embed fonts. It makes pdf suitable if you need correct representation on different systems. Unfortunately, LibreOffice pdfimport does not support the feature and often destroys documents (see bug 63834, bug 76500, bug 77830 and bug 79044 ). If it is impossible to import fonts, it would be useful at least preserve fonts to make LibreOffice usable for small changes in pdf. Difficulty is that usually whole font is not embedded, but only its subset is.
Reproducible with LO 4.3.2.2 (Win 8.1)
