MySQL Reference Manual - 4.0.20

11. Character Set Support

Improved support for character set handling was added to MySQL in Version 4.1. The features described here are as implemented in MySQL 4.1.1. (MySQL 4.1.0 has some but not all of these features, and some of them are implemented differently.)

This chapter discusses the following topics:

• What are character sets and collations?

• The multiple-level default system

• New syntax in MySQL 4.1

• Affected functions and operations

• Unicode support

• The meaning of each individual character set and collation

Character set support currently is included in the MySISAM, MEMORY (HEAP), and (as of MySQL 4.1.2) InnoDB storage engines. The ISAM storage engine does not include character set support; there are no plans to change this, because ISAM is deprecated.
