Thanks, Pablo. I ran the script but it made no difference. Scheherazade New was loaded with  ver: 2020.11.07 12:47 but not with ver: 2020.09.20 23:02

The console file for the latter shows:

selectfont      > the requested fallback font 'Scheherazade New' for typeface 'mainface' style 'rm' was ignored because no files where found.

And yet Scheherazade New sits beside Scheherazade (which 2020.09.20 finds) in ~/Fonts.
