Bonjour,

I have just made a fresh install of texlive 2019 and encountered a
problem with the diacritical marks of romanized sanskrit.

See this mwe (compile it with and without \setdefaultlanguage{sanskrit}) :

\documentclass[a4paper,twoside,11pt]{book}
\usepackage{fontspec}
\usepackage{polyglossia}
\setdefaultlanguage{sanskrit}
\setmainfont{FreeSerif}

\begin{document}
  ā ī ū ṛ ṝ ḷ ḹ ṭ ḍ ṅ ś ṣ ḥ
\end{document}

When you enable \setdefaultlanguage{sanskrit}, the diacritical marks
are awfull: macrons are moved on the right, dots under move on the
left, the dot on the "i" remains with the macron...

This did not occur with my previous 2018 version of texlive.

Thank you for attention.
