Storage space for this server character set is allocated on a byte basis rather than a character basis. This means that updates to a column defined as KANJISJIS can truncate because of this physical space.

SQL string manipulations of KANJISJIS data operate on a logical character basis and are performed by means of temporary conversion to Unicode. For this reason, KANJISJIS strings are limited to 32000 characters.
