U+1D366 Counting Rod Unit Digit Seven

U+1D366 was added in Unicode version 5.0 in 2006. 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. It is also used in the script Han. The codepoint has the numeric value 7.

The glyph is not a composition. Its East Asian Width is wide. In bidirectional text it is written from left to right. When changing direction it is not mirrored. The word that U+1D366 forms with similar adjacent characters prevents a line break inside it.

The Wikipedia has the following information about this codepoint:

Counting rods (筭) are small bars, typically 3–14 cm (1" to 6") long, that were used by mathematicians for calculation in ancient East Asia. They are placed either horizontally or vertically to represent any integer or rational number.
The written forms based on them are called rod numerals. They are a true positional numeral system with digits for 1–9 and a blank for 0, from the Warring states period (circa 475 BCE) to the 16th century.
