Polyglossia demands "Please define \devanagarifont with \newfontfamily" even if I use transliteration only.

[ppasedach]

I would like to use polyglossia for switching between hyphenation rules for English and Sanskrit, without needing to do any specific font setup for it:

\documentclass{article}
\usepackage{polyglossia}
\setdefaultlanguage{english}
\setotherlanguage{sanskrit}
\setotherlanguage{german}
\begin{document}
Something.
\textgerman{Etwas.}
\textsanskrit{kiṃcit.}
\end{document}

gives me the following error message:

! Package polyglossia Error: The current roman font does not contain the Devanagari script!
(polyglossia)                Please define \devanagarifont with \newfontfamily.

Of course I can follow the instruction in the error message and define a \devanagarifont, but if I'm intending to use latin transliteration of Sanskrit only this should not be necessary. Apparently if none of the other (indic) script options present in gloss-sanskrit.ldf is specifically selected, an option for transliteration not given, Devanagari is assumed as a default? hyph-sa.tex used by polyglossia for the hyphenation patterns is handling transliterated Sanskrit well.

Related also this thread, and this comment here.

This is fixed in current master (as opposed to 1.44).

Someone who can please close this ticket.

In current TeX Live 2020 I still get this. polyglossia 2020/04/08 v1.49 .

To clarify:

You need to use the script=Latin option (see polyglossia manual):

\documentclass{article}
\usepackage{polyglossia}
\setdefaultlanguage{english}
\setotherlanguage[script=Latin]{sanskrit}
\setotherlanguage{german}
\begin{document}
Something.
\textgerman{Etwas.}
\textsanskrit{kiṃcit.}
\end{document}

The default script of Sanskrit still is (and remains) Devanagari.
