U+1D2CA Kaktovik Numeral Ten

U+1D2CA was added in Unicode version 15.0 in 2022. It belongs to the block U+1D2C0 to U+1D2DF Kaktovik Numerals in the U+10000 to U+1FFFF Supplementary Multilingual Plane.

This character is a Other Number and is commonly used, that is, in no specific script. The codepoint has the numeric value 10.

The glyph is not a composition. It has no designated width in East Asian texts. In bidirectional text it is written from left to right. When changing direction it is not mirrored. The word that U+1D2CA forms with similar adjacent characters prevents a line break inside it.

The Wikipedia has the following information about this codepoint:

The Kaktovik numerals or Kaktovik Iñupiaq numerals are a base-20 system of numerical digits created by Alaskan Iñupiat. They are visually iconic, with shapes that indicate the number being represented.
The Iñupiaq language has a base-20 numeral system, as do the other Eskimo–Aleut languages of Alaska and Canada (and formerly Greenland). Arabic numerals, which were designed for a base-10 system, are inadequate for Iñupiaq and other Inuit languages. To remedy this problem, students in Kaktovik, Alaska, invented a base-20 numeral notation in 1994, which has spread among the Alaskan Iñupiat and has been considered for use in Canada.
