With (setq use-default-font-for-symbols nil), none of the following
forms make Emoji glyphs visible.
    (set-fontset-font t '(#x80 . #x10FFFF) "Noto Emoji")
or  (set-fontset-font t '(#x1F300 . #x1F6C5) "Noto Emoji")
or  (set-fontset-font t #x1F600 "Noto Emoji")

Also I found that OSMANYA DIGITs(U+104A0..U+104A9) are not displayed.
By default, OSMANYA LETTERs(U+10480..U+1049D) are displayed with Ebrima
font. But OSMANYA DIGITs are displayed as boxed hex numbers.
Explicitly evaluating (set-fontset-font t '(#x104A0 . #x104A9) "Ebrima"),
OSMANYA DIGITs are displayed as boxed hex numbers.
And evaluating (set-fontset-font t '(#x104A0 . #x104A9) "Noto Sans Osmanya"),
OSMANYA DIGITs are displayed as boxed hex numbers, too.
