Answer 1

Note - The below regex will match surrogate pairs (Supplemental), as well as single (Basic).

To see the hex version of what matched:
If the length of the match is 2, character 1 is a low surrogate, character 2 is a high surrogate. Just format each character to hex, and join them in a string.

You could try to match some emoji via hex ranges.

This regex matches these 1,114 emoji characters.

Note - this excludes characters in the range \x00-\x7f; for some reason there are emoji in this range like 0-9.. (using \p{Emoji=yes}).

The below regex will match these emoji.
