Testing dev-actualtext.pdf sent by JK
* Adobe Acrobat Reader XI on Windows 10
o Does not highlight text fully

highlights only beginning of the word containing the letter
o COPY paste to NOTEPAD++, OPENOFFICE WRITER works correctly,
o Save as TXT file does not work correctly - only saves ... in it,
not the actual unicode text which can be copied
So it looks like Acrobat makes use of the ActualText for Search and
Copy, but sadly its "Save as Text" doesn't support Unicode.
I'm pleasantly surprised to see the Gmail previewer also handles it.
The others (Foxit, Edge) sound like they're just working from the glyph
stream, which is basically doomed to failure.
For a further data point, I tried Evince (Document Viewer) on Ubuntu
15.10, and found that Copy and Search work well; it looks like it is
using the ActualText correctly. This is thanks to the poppler library, I
believe. The (poppler-based) "pdftotext" tool was also able to extract
the Unicode text correctly from the PDF, although "pdftohtml" didn't do
so well.
One issue with Evince is that drag-selecting text to highlight it (as
for Copy/Paste) looks bad: the highlighting completely obscures the
selected text, although it will end up being copied correctly.
Interestingly, its highlighting of search results doesn't suffer from
this problem, and it even makes a fair attempt (not completely accurate)
at highlighting specific letters within a word, not just entire words.

Ah, right... as there are no spaces between the kanji, they'll end
up in the same text object. That's a shortcoming of how the current
implementation works, for scripts that don't use inter-word spaces.
In either case, copy&paste actually gives you the whole text, even
though AAPro only highlights half of it, I guess?
