Hi Werner,
Thanks for all this really precious information. Noto Sans is really good.
But I am barking up the wrong tree it appears to me. Symbola and Noto Sans cover this Unicode block, but the semisharp is the form of a sharp with a 4 for quartersharp. I was hoping to find the symbol I use, which is the lilypond semisharp symbol.
Do I need to look at Bravura from SMuFL perhaps?
