I don't think this is a limitation of poppler so much as the way that
pdf annotations work. Typically, the subject/text field is not populated
by the text of the highlighted region. Rather, a highlight annotation
specifies bounds, color, style, etc. Basically what Repligo does (I
wouldn't recommend using it, as it is closed source and severely out of
date) is to grab the text *at the time of highlighting* and add it to
the notes field. I don't know of any other annotation tool that does the
same thing. Applications built on poppler could do it, though they
currently do not.

For extracting the text of highlighted regions *after the fact*, I've
had good luck with this script that relies on the pdf-reader gem for
