No, that is correct. If you are able to set the text editor to use Linux
Libertine G you probably would not see corruption. Not certain, but I think the
issue was with your LibreOffice's generation of the /ToUnicode mappings.
Below are the /ToUnicode charts for the MS PDF and Phantom PDF for the test
string "The fire flying coffee left Quickly"
With Linux Libertine G is encoded in both PDF generators as
'<E049>e <FB01>re <FB02>ying co<FB00>ee le<E039> <E048>ickly.'
glyph positioning omitted of course.
When that text is copied to a text editor--the text editor must able to be set
to use the same Linux Libertine G font. If not the PUA glyphs (E039, E048,
E049) can not be rendered, the same for needing to support the Unicode
Alphabetic Presentation Forms (here just FB00-ff, FB01-fi, FB02-fl).
Both PDF generators look to have correctly generated /ToUnicode charts, the PUA
are mapped and with a text editor using Linux Libertine G (I prefer BablePad
for this)--the strings are fully rendered. Notice the sequence of glyphs added
to the /ToUnicode chart depends on the PDF generator.
