Multibyte characters

The following convention shows abstractly how multibyte characters are stored:

A1...An

One to four identical uppercase letters, each followed by a different superscript number, represent one multibyte character. The superscripts show the first to the nth byte of the multibyte character, where n has values 2 - 4. For example, the following symbols represent a multibyte character that consists of 2 bytes:

A1A2

The following notation represents a multibyte character that consists of 4 bytes (the maximum length of a multibyte character):

A1A2A3A4

The next example shows a string of multibyte characters in an SQL statement:

CREATE DATABASE A1A2B1B2C1C2D1D2E1E2;
