U+068A "ڊ" Arabic Letter Dal with Dot Below Unicode Character

U+068A "ڊ" Arabic Letter Dal with Dot Below is a variant of the Arabic letter "د" (dal) that features a single dot placed beneath the main body of the character. This diacritical modification is used in specific Arabic-script languages, most notably in Sindhi and occasionally in other regional orthographies, to represent a distinct consonantal sound that differs from the plain dal. In Sindhi, for example, it typically denotes a voiced retroflex stop or flap sound, which is not present in standard Arabic. The character is encoded in the Unicode Standard as part of the Arabic script block, allowing for accurate digital representation of languages that require this specialized letter for proper phonetic and orthographic expression.
