How to support full Unicode in MySQL databases?

Since utf8mb4 is fully backwards compatible with utf8, no mojibake or other forms of data loss should occur. (But you have a backup, right?) This is probably the most tedious part of the whole upgrading process. When converting from utf8 to utf8mb4, the maximum length of a column or index key is unchanged in terms of bytes.

What kind of character set does MySQL support?

MySQL supports these Unicode character sets: utf8mb4: A UTF-8 encoding of the Unicode character set using one to four bytes per character. utf8mb3: A UTF-8 encoding of the Unicode character set using one to three bytes per character. utf8: An alias for utf8mb3 .

Is there a BOM for UTF-8 in MySQL?

MySQL uses no BOM for UTF-8 values. Client applications that communicate with the server using Unicode should set the client character set accordingly (for example, by issuing a SET NAMES ‘utf8mb4’ statement). Some character sets cannot be used as the client character set.

How many UTF-8 symbols can be stored in MySQL?

MySQL returned a warning message, too: Turns out MySQL’s utf8 charset only partially implements proper UTF-8 encoding. It can only store UTF-8-encoded symbols that consist of one to three bytes; encoded symbols that take up four bytes aren’t supported.
