isIdeographic

A Boolean value indicating whether the scalar is considered to be a CJKV (Chinese, Japanese, Korean, and Vietnamese) or other siniform (Chinese writing-related) ideograph.

ss7UnicodeO6ScalarV10PropertiesV13isIdeographicSbvpWhat are these?

FNV24: [96T0M]

This property roughly defines the class of “Chinese characters” and does not include characters of other logographic scripts such as Cuneiform or Egyptian Hieroglyphs.

This property corresponds to the “Ideographic” property in the Unicode Standard.
