Function/description: [To identify the control to indicate the function not to join two elements with zero-width between them.,This symbol should be used in the orientation shown.]
Additional information:

• This symbol corresponds to the hexadecimal code point U+200C named ZERO WIDTH NONJOINER of the ISO/IEC 10646-1.
• This may occur in a formally cursive script (such as Arabic) in a context where it breaks a cursive connection as required for orthographic rules, as in the Persian language, for example. It also may occur in Indic scripts in a consonant-conjunct context (immediately following a virama), to control required display of such conjuncts. (Quoted from IETF/RFC 5892, Appendix A.1.) It also may occur in German compound words at the border of the constituents, to prevent ligatures there according to German typesetting rules.
