U+0959 "ख़" Devanagari Letter Khha Unicode Character

U+0959 "ख़" Devanagari Letter Khha is a specific glyph within the Devanagari script used to represent the aspirated voiceless velar fricative sound /kʰ/, which is distinct from the common "ka" (क) and is often employed in writing loanwords from Persian, Arabic, and other languages into Hindi and Nepali, such as in the words "ख़त" (khat, meaning letter) or "ख़ास" (khaas, meaning special). It is visually similar to the letter "ख" (Kha) but is conventionally marked with a dot (nukta) placed beneath it in many typefaces to differentiate the phonetic value, making it a crucial character for accurate transliteration and transcription in South Asian languages.
