In this case, an image really is worth a thousand words:
That links to the question What sound did the letter ℵ encode in ancient Hebrew, and why did it morph into the greek vowel Α?
The original image is at https://languages.codidact.com/ca/posts/281765.png
Notice that, in the image, "ℵ" U+2135 displays as a question mark, but "Α" (which really is a Greek uppercase alpha U+0391, not the visually similar Latin uppercase A U+0041) displays correctly.
I believe that this is a bug, and that ℵ should also render correctly in this case.
More generally, if we're going to go around replacing characters that for some reason can't be rendered in the image, it's probably better to use "�" U+FFFD for that purpose.
