As @SDGGiesbrecht has answered, and also as I've answered in the other thread you posted on the same topic, there is no such thing as "SF Symbols codepoint properties."
SF Symbols is an icon library implemented as a font; it makes use of the Unicode private use area for its glyphs. Fonts don't have Unicode scalar properties, Unicode scalars do. Unicode scalars are not specific to any font.
The makers of SF Symbols can choose to encode whatever glyphs they want in the private use area, just like they could choose to name their SVG files whatever they want if they offered the icons as a set of SVG files. You can use Unicode.Scalar.Properties to tell you certain properties about a Unicode scalar in the private use area, just like you can use an SVG library to tell you certain properties about an SVG file. But Unicode.Scalar.Properties cannot help you identify what any symbol represents in SF Symbols just because it's an icon library implemented as a font, in exactly the same way that an SVG library can't help you identify what any symbol represents in an icon library implemented as a set of SVG files. (Actually, the analogy is imperfect, because an SVG library would be able to read the actual SVG file in question where there could be custom metadata, whereas Unicode.Scalar.Properties has nothing to do with the font itself.)
