Chapter 10. Character Set Support

MySQL includes character set support that enables you to store data using a variety of character sets and perform comparisons according to a variety of collations. You can specify character sets at the server, database, table, and column level. MySQL supports the use of character sets for the MyISAM, MEMORY, NDBCluster, and InnoDB storage engines.

This chapter discusses the following topics:

  • What are character sets and collations?

  • The multiple-level default system for character set assignment

  • Syntax for specifying character sets and collations

  • Affected functions and operations

  • Unicode support

  • The character sets and collations that are available, with notes

Character set issues affect data storage, but also communication between client programs and the MySQL server. If you want the client program to communicate with the server using a character set different from the default, you'll need to indicate which one. For example, to use the utf8 Unicode character set, issue this statement after connecting to the server:

SET NAMES 'utf8';

For more information about character set-related issues in client/server communication, see Section 10.4, “Connection Character Sets and Collations”.
