U+0660 "٠" Arabic-Indic Digit Zero Unicode Character

U+0660 "٠" Arabic-Indic Digit Zero is a distinct numeral used in Arabic script contexts, primarily in the Eastern Arabic numeral system common in countries like Egypt, Iran, and Pakistan, where it represents the number zero. Unlike the Latin digit '0', which is often circular, this character is typically rendered as a small filled circle or dot, and it appears in the Unicode block for Arabic, separate from the Western Arabic digits (0 through 9) to preserve typographic and cultural differences in mathematical notation. Its usage ensures proper digital representation of numbers in languages that employ the Arabic script, such as Persian, Urdu, and Arabic itself, where it aligns with local numeral forms.
