U+0640 "ـ" Arabic Tatweel Unicode Character

U+0640 "ـ" Arabic Tatweel is a special typographic mark used in Arabic script to visually lengthen a word or to justify text by connecting letters without adding spaces. It appears as a horizontal dash-like stroke that can be inserted between the base letters of a word, allowing calligraphers and typesetters to adjust the spacing for aesthetic or alignment purposes in manuscripts and digital layouts. Unlike a standard character that represents a sound, the Tatweel has no phonetic value and is purely a formatting glyph, commonly employed in formal writing, signage, or traditional calligraphy to create a more balanced or decorative line of text.
