Indic Syllabic Category - Non Joiner

Non Joiner is a character classification that marks a symbol explicitly preventing cursive joining between adjacent characters in scripts like Arabic. This value indicates that the character, typically a visible or invisible control, forces a break in the otherwise automatic ligature or connection pattern, ensuring that two letters remain visually separate. It is crucial for accurate rendering of words where a mandatory pause or distinction is required, such as in certain Persian or Urdu contexts, and it overrides the default joining behavior determined by each letter’s inherent form. The specific value applies to characters that act as a barrier, not to letters that inherently lack connection, and it is distinct from a zero-width non-joiner, which is an invisible format character serving a similar but separate function.
