If a character in a particular encoding spans multiple bytes, the character-based string functions can process each character as a single unit as opposed to a sequence of bytes.

如果采用特殊编码的某个字符的长度跨越了多个字节，则基于字符的字符串函数可以将每个字符处理为一个单元而不是一个字节序列。

Prior to DB2 UDB V8.2, a Unicode database could only be defined with the collating sequence IDENTITY, which means that the characters are compared by their byte encoding.

在DB 2 UDB V8.2之前，Unicode数据库只能定义为排序次序identity，这意味着按照字节编码对字符进行比较。
