U+1D374 Ideographic Tally Mark Three

U+1D374 was added in Unicode version 11.0 in 2018. It belongs to the block U+1D360 to U+1D37F Counting Rod 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 3.

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+1D374 forms with similar adjacent characters prevents a line break inside it.

The Wikipedia has the following information about this codepoint:

Tally marks, also called hash marks, are a form of numeral used for counting. They can be thought of as a unary numeral system.
They are most useful in counting or tallying ongoing results, such as the score in a game or sport, as no intermediate results need to be erased or discarded. However, because of the length of large numbers, tallies are not commonly used for static text. Notched sticks, known as tally sticks, were also historically used for this purpose.
