How to show newer unicode characters in macOS?

[Oneechan69]

For instance, ▎(Left One Quarter Block, [U+258E](https://www.compart.com/en/unicode/U+258E)) can be shown in macOS but not 🮇 (Right One Quarter Block, [U+1FB87](https://www.compart.com/en/unicode/U+1FB87)), not even in the Character Viewer. That character was introduced in Unicode 13 in 2020. Any ideas to show *all* newer unicode characters, perhaps even patching fonts to do so.

A.) add the alternate input Unicode Hex Input

B.) Use this Automator action.
