Here is how U+261E (manicule) and U+00B6 (pilcrow) are displayed in Pages:
As you can see, all the U+261E and U+00B6 glyphs looks pretty the same across Menlo, Monaco and Courier New (with the exception of pilcrow in Courier New) and across Helvetica Neue and Gill Sans, and for this reason it is not clear to me whether these glyphs are really from their respective fonts or macOS has "borrowed" them from some another font or from multiple fonts (a technique which is known as font substitution).
How I can verify it?
