Zero-width joiner

From Wikipedia, the free encyclopedia

The zero-width joiner (ZWJ) is a non-printing character used in the computerized typesetting of some complex scripts, such as the Arabic script or any of the Indic scripts. When placed between two characters that would otherwise not be connected, a ZWJ causes them to be printed in their connected forms. In some cases, such as the second Devanagari example below, the ZWJ follows the second character, rather than the first.

When a ZWJ is placed between two emoji characters, this can also result in a new form being shown, such as the four-person family emoji which is made up of the man, woman, girl, and boy emoji.[1]

The character's code point is U+200D zero width joiner (HTML ‍ · ‍). In the InScript keyboard layout for Indian languages, it is typed by the key combination Ctrl+Shift+1. However, many layouts use the ']' key for this character.[2]
