pandoc-xepersian is a pandoc filter that converts english text to xepersian compatible version
This is just a latex filter
In order to convert persin Markdown to xepersian and applying this filter you must copy pandoc-xepersian.py into current directory, following command should be used:
pandoc --latex-engine=xelatex -R -i in.md -o out.tex --filter ./pandoc-xepersian.py
Please make sure that the filter file is executable.
It seems that in Windows OS filter usage resutls in encoding problems and it seems to be windows cmd and powershell's bug.
