Answer 1

Please use utf8mb4 when you insert to table

set username utf8mb4; INSERT INTO table_name (aaa,VAL);

you can just do it by alter table field from phpmyadmin and set type to utf8mb4 .

mysqli_query("SET character_set_results=utf8mb4", $db);

Sometimes MySQL's utf8 does not support.This is because of a small number of Chinese characters that require 4-byte UTF8 characters.So utf8mb4 used.

Answer 2

change that column's charset/collection from Default charset to utf8

then you can insert anything in that column
