Emacs also displays tofu if it finds no suitable font. What you
describe sounds like Emacs found some font that claimed to have a
glyph for this codepoint, but the glyph displays as blank. Which is,
of course, in contradiction with the "no font available" part, so I
admit I don't understand what happened on your system. Was that in
"emacs -Q"?
Yes it was.
Does this empty display happen with every character for which you have
no fonts? For example, what about this string: 𓂋𓏤𓈖𓆎𓅓𓏏𓊖?
On my system, characters for which Emacs cannot find a font display as
"tofu": small squares that show the codepoint of the character in
hex. That's what should happen by default in those cases.
I cut and pasted that string from Apple Mail to Emacs 28 -Q on macOS 11.6.5
and saw this:
