The zero width non joiner (ZWNJ) is a
non-printing character used in the computerized
typesetting of some
cursive script, Korean
hangul or
Persian script. When placed between two characters that would otherwise be connected, a ZWNJ causes them to be printed in their final and initial forms, respectively. This is also an effect of a
space character, but a ZWNJ is used when it is desirable to keep the words closer together. The ZWNJ is represented in
Unicode is U+200C, and can be represented in HTML as ‌ or ‌.
