Both indications are correct :)
Later format PDFs are capable of storing an explicit character string, but
whether or not this happens depends on how the PDF is made. A PDF distilled
from a print stream is not going to contain explicit character strings, but
a character string can be derived from the glyphs, with varying degrees of
accuracy. Some PDF generators might include explicit character strings, but
other may not. Some might do so automatically, others might do so only
under certain conditions.

indifferent to it. - Terry Eagleton
