U+200C "‌" Zero Width Non-Joiner Unicode Character

U+200C "‌" Zero Width Non-Joiner is an invisible control character used in text processing to prevent two adjacent characters from forming a cursive ligature or connection in scripts such as Arabic, Persian, or Devanagari. When inserted between two letters that would normally join together in a continuous stroke, it explicitly breaks that link, allowing them to appear as separate, disconnected forms. This function is essential for accurately writing certain words or phrases, such as distinguishing between a compound word and a single word where a join would be incorrect, and it also aids in proper line breaking and character spacing without adding any visible glyph or width to the text.
