Sanskrit/Devanagari fonts not exported to org-pdf output

[Zenny]

Hi,

I tried to export to pdf with the following:

#+LATEX_HEADER: \usepackage{polyglossia}
#+LATEX_HEADER: \usepackage{fontspec}
#+LATEX_COMPILER: xelatex (also tried with lualatex)
#+LATEX_HEADER:  \setmainlanguage{english}
#+LATEX_HEADER:  \setotherlanguage{sanskrit}
#+LATEX_HEADER:   \newfontfamily\devanagarifont{Noto Serif Devanagari}

स्वस्ति सत्यं वचति

but it exports alright to odt, and even pandoc exports alright directly from org file to docx file, but the Sanskrit/Devanagari fonts are skipped (blank) in pdf output when exported directly from org file with C-c C-e l o.

Already tried with the solutions provided in  https://emacs.stackexchange.com/questions/27576/exporting-devanagarai-text-from-org-mode-to-latex, but there are no such options (variables defined) after 'M-x customize-group' available.
