Does MySQL support Unicode?
MySQL supports multiple Unicode character sets: utf8mb4 : A UTF-8 encoding of the Unicode character set using one to four bytes per character. utf16 : The UTF-16 encoding for the Unicode character set using two or four bytes per character. Like ucs2 but with an extension for supplementary characters.
How do I insert a Unicode character into MySQL?
In order to insert Unicode characters in MySQL, you need to create a table with Unicode support, select the appropriate encoding/collation settings, and specify the charset in the MySQL connection. Then, you can proceed and employ PHP code to insert Unicode as you please.
How do I make MySQL handle UTF-8?
- use SET NAMES utf8 before you query/insert into the database.
- use DEFAULT CHARSET=utf8 when creating new tables.
- at this point your MySQL client and server should be in UTF-8 (see my. cnf ). remember any languages you use (such as PHP) must be UTF-8 as well.
What is the difference between utf8mb4_general_ci and utf8_general_ci?
utf8mb4_unicode_ci is based on the official Unicode rules for universal sorting and comparison, which sorts accurately in a wide range of languages. utf8mb4_general_ci is a simplified set of sorting rules which aims to do as well as it can while taking many short-cuts designed to improve speed.
What encoding does MySQL use?
Although MySQL supports the UTF-8 character encoding set, it is often not used as the default character set during database and table creation. As a result, many databases use the Latin character set, which can be limiting depending upon the application.
What MySQL collation should I use?
It is best to use character set utf8mb4 with the collation utf8mb4_unicode_ci . The character set, utf8 , only supports a small amount of UTF-8 code points, about 6% of possible characters. utf8 only supports the Basic Multilingual Plane (BMP).
What is charset utf8mb4?
MySQL supports multiple 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.
How do I change Unicode in MySQL?
To change the character set encoding to UTF-8 for the database itself, type the following command at the mysql> prompt. Replace dbname with the database name: ALTER DATABASE dbname CHARACTER SET utf8 COLLATE utf8_general_ci; To exit the mysql program, type \q at the mysql> prompt.
Is UTF-8 and ASCII same?
UTF-8 encodes Unicode characters into a sequence of 8-bit bytes. Each 8-bit extension to ASCII differs from the rest. For characters represented by the 7-bit ASCII character codes, the UTF-8 representation is exactly equivalent to ASCII, allowing transparent round trip migration.
Should I use utf8mb4?
If you need to use MySQL or MariaDB, never use “utf8”. Always use “utf8mb4” when you want UTF-8. Convert your database now to avoid headaches later.
What is the best collation for MySQL?
What is utf8 collation?
A collation is a property of string types in SQL Server, Azure SQL, and Synapse SQL that defines how to compare and sort strings. In addition, it describes the encoding of string data. If a collation name in Synapse SQL ends with UTF8, it represents the strings encoded with the UTF-8 encoding schema.
How to properly store and display Unicode in MySQL?

How to choose your MySQL encoding and collation?
– First the character set name. – Then which language it is for, for example ja for Japanese. A special “language” is binary which mean each byte is compared directly one by one. – Then whether it is a UCA 9.0.0 based collation. – Then up to three modifiers depending on whether it is accent and/or case sensitive or insensitive.

Why do we need ASCII, instead of Unicode?
– ASCII is a large part of computer history and vast majority of software ever written for computers are in ASCII. – It’s true that ASCII is a sub-set of UTF-8, and you can consider any ASCII files as UTF-8, but it’s because of the importance of ASCII that you have this – ASCII is the maximal intersection of many code pages and encodings besides UTF-8.
