PDF has the /ActualText(...)  replacement tagging feature.
This allows you to capture a sequence of content characters
and declare the whole collection to be equivalent to a single
(or sequence of) Unicode point(s).

Searching and copying is *supposed to* use these replacements,
when available. Unfortunately, not all PDF browsers actually
do this yet.
