The shortcut inserts a distinct mathematical character rather than restyling ordinary Arabic ش.
What does the double-struck Arabic shīn mean?
It is the mathematical form of Arabic ش, called shīn.
Arabic math uses letter shapes as formula symbols. This character is one of six forms found in Arabic mathematical handbooks; the equation or textbook convention gives it its particular role.
The notation's history predates Unicode: evidence for Arabic mathematical symbols reaches at least the 14th century, and mathematicians Ibn al-Banna and al-Qalasadi used symbols in the 15th century. The letter forms draw on Arabic writing used in manuscripts and traditional mathematics books, rather than one modern design.
Why doesn't 𞺴 join Arabic letters?
Math forms stay separate rather than joining into words.
In ordinary Arabic, ش connects to neighboring letters and changes shape by position. This mathematical form stays isolated, preserving its distinct role in formulas.
A 2006 W3C guide illustrates regional differences: Maghreb math examples flow right to left, Moroccan examples follow French-style direction, and Mashreq examples use localized Arabic letters and number forms. Read this character within the equation's local convention.

1Why does 𞺴 show as a box on some devices?
Because that device's fonts have no glyph for it. The character is still correct and still copies correctly — the box is a missing glyph, not a broken character.
