U+0768 "ݨ" Arabic Letter Noon with Small Tah Unicode Character

U+0768 "ݨ" Arabic Letter Noon with Small Tah is a specialized letter used in certain Arabic-based orthographies, most notably in the Punjabi language as written in the Shahmukhi script, where it represents a retroflex nasal sound (usually transliterated as "Ṇ" or "ṇ") that is not found in standard Arabic. This character is formed by combining the base Arabic letter Noon (ن) with a small version of the letter Tah (ط) placed above it, which serves as a diacritical mark to indicate this phonetic distinction. Its inclusion in the Unicode Standard ensures that digital text processing and display can accurately represent the unique sounds of languages like Punjabi, helping preserve their linguistic identity.
