# luaotfload: can't find font after updating font database

I have installed a new font "MCS Diwany1 S_U adorned." with xelatex there is no problem but with lualatex a file like this

\documentclass[11pt]{report}
\usepackage{fontspec}

\begin{document}
\pardir TRT \textdir TRT
أهلا

\end{document}


Produces an error ! fontspec error: "font-not-found". I tried to execute in the command line

luaotfload-tool --update --force


Without effect, and the result is

luaotfload | db : Unknown format: "", skipping.

• FontForge complains loudly that the font name is invalid. I’ve seen it complain about other fonts that luatex manages to use, but there are lots of complaints when I open this font in FontForge. – Thérèse Nov 2 '18 at 18:39
• I can't use this font with xelatex but at least the system can find the font. – Salim Bou Nov 2 '18 at 18:56
• Maybe renaming the font in FontForge would help? – Thérèse Nov 2 '18 at 18:58
