[XeTeX] popup windows in XeLaTeX?

[Janusz S. Bień]

Hi!

I use regularly XeLaTeX, but for a specific text I switched to LuaLaTeX
because using the engine, together with ocgx, seemed the simples way to
get footnotes in the form of the popup windows:

Now I run into some problems with LuaTeX (wrong encoding of Polish
letters in the outline); it seems the solution exists but is not a
straightforward one.

Processing the text with XeLaTeX fails on \pdfstartlink, I am aware of a
thread concerning emulating it:

https://tex.stackexchange.com/questions/86027/how-to-emulate-pdfstartlink-and-pdfendlink-with-xetex

I would appreciate your advice what is the most easy and/or elegant way
to solve the problem.

Best regards

Janusz

P.S. I'm sorry for sending it first by mistake to xetex-request.
