We can highlight character sets at the server, database, table, and column level. A Character-set allows us to store data through a variety of character sets and do comparisons according to a variety of collations. A collation is a set of rules for comparing characters in a character set. A character set is a set of specific symbols and encoding techniques.Two character sets cannot have the same collation. Each character set in MySQL might have more than one collation, and has, at least, one default collation. A MySQL collation is a well-defined set of rules which are used to compare characters of a particular character-set by using their corresponding encoding. MySQL Collation has always been a mystifying topic for beginners of MySQL learners.

To find the maximum of the currently used collation IDs, use this query: SELECT MAX(ID) FROM INFORMATION_SCHEMA.COLLATIONS You should not use UTF-8 because MySQL’s. If you elect to use UTF-8 as your collation, always use utf8mb4 (specifically utf8mb4unicodeci). If you’re using MySQL 8.0, the default charset is utf8mb4. The range of IDs from 1024 to 2047 is reserved for user-defined collations. If you’re using MySQL 5.7, the default MySQL collation is generally latin1swedishci because MySQL uses latin1 as its default character set. You must assign a unique ID number to each collation. Putting that all together, the following might work (but again, I have no way to test): The answer by Xing Zhang resolves the issue, and the only problem appears to have been the collation ID.
