Hi Hans, everybody

there’s a bug report concerning one of the Noto fonts:

    https://github.com/lualatex/luaotfload/issues/292

Fonts are freely available: https://www.google.com/get/noto/
Quick link to the example translated to Context:

    https://bitbucket.org/phg/lua-la-tex-tests/src/tip/context/cnt-urdu.tex

Those features are what’s applied by Luaotfload by default for
Arabic.

Best,
Philipp
