Consider following tex and bib files. As you see the second bib item is not rendered correctly. Is there any solution?
The squares are not the only problem, indeed all character of Persian item have not been rendered correctly. The out put should be similar to what you can see in the source code. Using tex.stackexchange.com/a/97304/13747 I can add Persian in the body of document but I don not know how to apply that solution to Persian bibliography items.
main.tex
\documentclass{article}
\usepackage{fontspec}
\usepackage{bidi}
\setmainfont{Times New Roman}
\begin{document}
Test \cite{noormags145485,cour71}
\bibliography{main}
\bibliographystyle{plain}
\end{document}
main.bib
