U+0690 "ڐ" Arabic Letter Dal with Four Dots Above Unicode Character

U+0690 "ڐ" Arabic Letter Dal with Four Dots Above is a modified letter used primarily in certain Arabic-based alphabets, such as those for writing the Sindhi language, where it represents a voiced alveolar implosive consonant, a sound distinct from the standard Arabic "د". This character is formed by adding four dots above the base Arabic letter "د" (dal), indicating a phonetic variation or a distinct phoneme from the parent script. Its inclusion in Unicode ensures proper digital representation and text processing for languages that rely on this specific diacritical modification.
