I used following code to add bullet but it's seems has some problem with XeLatex. It shows line (dash) instead of bullet. How can I fix this?
\begin{itemize} \item \textit{irBlogs} \item \textit{Hamshahri} \end{itemize} result is something like below:


\documentclassand ending at\end{document}which recreates your issue. Note that there are several packages which might change the symbol used byitemizeand that a nesteditemizecan have a different symbol from an unnested one. You can specify the used symbol (if it should be different than the rest) using the optional argument\item[$\bullet$]but using this for every item is tedious.
