MySQL's `utf8` encoding cannot store all unicode codepoints, only those
that will fit in 3 bytes (codepoints 0x0000 to 0xFFFF).
[https://stackoverflow.com/questions/30074492/what-is-the-difference-
between-utf8mb4-and-utf8-charsets-in-mysql See here for more info]

We should recommend the `utf8mb4` encoding, which fully supports unicode,
to avoid users running into cryptic errors like [https://www.eversql.com

{{{
