It seems to be the case with all superscripts but apparently only at
the end of a line. I tried this:
\begin{verse}
\dev{के\\ जे\\ जँ\\ जेजेजे\\ जँजँजँ\\ र्जर्जर्ज}
\end{verse}
Here is the result:

Raghindi places accents correctly but does not produce the right glyph
रृ for "ra + vocalic r". I have been testing it for a short time, I hope
there aren't any other flaws.
Nobody at SIL is preparing a fine Nagari font by chance? For Sanskrit
(including Vedic) a flawless font is still missing.
Best wishes,
Yves
