LuaLaTeX error when compiling visual counter

Question

I asked a question about visual counters in beamer, for which I got this answer. Now I need to compile it by LuaLaTeX in order to use the package luapersian(below code), but it returns some errors.
Luapersina can be downloaded from this link.

Please give us some code. I don't use Persian and don't want to find out how to do that in LaTeX just in order to help here with some compilation issue. And what are the errors? — LaRiFaRi, Apr 15 '14 at 15:21
Yes, please, edit your post and include all the relevant TeX codes, otherwise we are wildly guessing what might go wrong. — Malipivo, Apr 15 '14 at 16:20
Welcome to TeX.SX! Please help us to help you and add a minimal working example (MWE) that illustrates your problem. It will be much easier for us to reproduce your situation and find out what the issue is when we see compilable code, starting with \documentclass{...} and ending with \end{document}. — Martin Schröder, Apr 16 '14 at 11:58
Your example document fails to compile (even without luapersian); something seems to be wrong. Does it compile for you as is (without loading luapersian)? — Gonzalo Medina, Apr 16 '14 at 13:36
yes, just compile it using: lualatex -interaction=nonstopmode -synctex=-1 %.tex — user49875, Apr 16 '14 at 18:23

Caveat emptor I don't have \usepackage{luapersian}, so I only tried to compile with lualatex

Your visible code looks fine, but when copying from your question above there where tons of invisible characters in front of after the visible text. After removing all of them, you example compiles fine with lualatex
