U+077F "ݿ" Arabic Letter Kaf with Two Dots Above is an extended Arabic letter used primarily in historical or specialized orthographies for languages such as early Sindhi or other regional scripts, where it represents a distinct sound often akin to a voiceless velar or palatal fricative. Its two dots above the baseline modify the base letter "kaf" to indicate a phonetic variant not covered by the standard Arabic alphabet. This character falls within the Arabic Supplement block of Unicode, which was added to support diverse writing traditions beyond those of the core Arabic script. As a result, it is rarely encountered in modern everyday text but is crucial for accurate digital representation and scholarly work on historical manuscripts and linguistic documentation.
