I'm looking for a way to get popup references when hovering with the mouse cursor over the references in my papers. I looked around on this forum and found this question and hpesoj626's answer very useful:
However, it's imperative that I can use opentype/truetype fonts in my document, including CJK. Previously, I've used XeLaTeX. I've realized that XeLaTeX is not an option for this kind of thing, since it doesn't produce PDFs in the same way. However, there is LuaLaTeX, which, as far as I understand, works similarly to pdflatex?
For my own purposes (unicode, CJK) I could just as well use LuaLaTeX (although I haven't tried this yet).
What I cannot use is simple pdflatex, which is what is used in the Perl script provided in hpesoj626's answer to the question I linked to above.
Is there a way to make this script work with unicode and opentype fonts?
