IDEOGRAPHIC SPACE (U+3000)
CHARACTER(n) CHARACTER SET GRAPHIC
GRAPHIC data can also be defined as GRAPHIC(n) or VARGRAPHIC(n); however, for best practice, define all GRAPHIC data as CHARACTER(n) CHARACTER SET GRAPHIC or VARCHAR(n) CHARACTER SET GRAPHIC.
All characters named as letters in this subset of UNICODE are considered as such, and are candidates for uppercasing.
For details about the GRAPHIC server character set, see International Character Set Support.
CLOBs do not support the GRAPHIC server character set.
