Hi,
1. Start emacs -Q [28.0.91 or 28.0.60]
2. eval-buffer containing:
(require 'cl-lib)
(require 'cl-extra)
(let ((str "The quick brown fox jumps over the lazy dog
´`''\"\"1lI|¦!Ø0Oo{[()]}.,:; ")
(font-families (cl-remove-duplicates
(sort (font-family-list)
(lambda(x y) (string< (upcase x) (upcase y))))
:test 'cl-equalp)))
(dolist (ff font-families)
(insert
(propertize str 'font-lock-face `(:family ,ff)) ff "\n"
(propertize str 'font-lock-face `(:family ,ff :slant italic)) ff
"\n")))
