Incorrect string value error for unconventional characters

So I'm using a wrapper to fetch user data from instagram. I want to select the display names for users, and store them in a MYSQL database. I'm having issues inserting some of the display names, dealing with, specifically, an incorrect string value error:

Now, I've dealt with this issue before with accent marks, letters with umlauts, etc. The solution would be to change the collation to utf8_general_ci under the utf8 charset.

So as you can see, some of the display names I'm pulling have very unique characters that I'm not sure mySQL can recognize at all, i.e.:

ᛘ𝕰𝖆𝖗𝖙𝖍𝕾𝖕𝖎𝖗𝖎𝖙𝖚𝖘𐂂®

So I receive:

Error Code: 1366. Incorrect string value: '\xF0\x9D\x99\x87\xF0\x9D...' for column 'dummy' at row 1

Here's my sql code

CREATE TABLE test_table(    id INT AUTO_INCREMENT,    dummy VARCHAR(255),    PRIMARY KEY(id));INSERT INTO test_table (dummy)VALUES ('ᛘ𝕰𝖆𝖗𝖙𝖍𝕾𝖕𝖎𝖗𝖎𝖙𝖚𝖘𐂂®');

Any thoughts on a proper charset + collation pair that can handle characters like this? Not sure where to look for a solution, so I come here to see if anyone dealt with this.

P.S., I've tried utf8mb4 charset with utf8mb4_unicode_ci and utf8mb4_bin collations as well.
