For UNICODE, GRAPHIC and KANJISJIS server character sets, the functions operate on a logical character basis, except for the functions that are sensitive to the ANSI mode vs. Teradata mode switch.

Although the storage space for KANJISJIS is allocated on a physical basis and is not ANSI compatible, all string operations on this type operate on a character basis as dictated by ANSI.
