Vertical presentation form of the solid (non-ring) full stop, 0xA1C0 (hangyol 01-32) in KPS 9566. A corresponding form is not included amongst Unicode's vertical presentation forms. This character is usually mapped to the approximate U+02D9 DOT ABOVE, although it has at times been mapped to private use codes U+E100 (in ISO/IEC JTC 1/SC 2/WG 2 N 2056 Annex B), U+F000 or U+F100 (both of the latter are supported by fonts from Red Star OS 2.0, but not 3.0).
