Herbert Voss was so kind to change the libertinus-otf.sty

It has now definitions for

   \newunicodechar{∂}{\delta}
   \newunicodechar{∆}{\Delta}
   \newunicodechar{π}{\pi}
   \newunicodechar{∏}{\Pi}
   \newunicodechar{µ}{\mu}
   \newunicodechar{Ω}{\Omega}
   \newunicodechar{∑}{\Sigma}
   \newunicodechar{Θ}{\Theta}
   \newunicodechar{θ}{\theta}
   \newunicodechar{ϑ}{\vartheta}


which can now be inserted directly via the keyboard. Further ones are 
definable via the LyX-preamble.
