Khē different from kaph
Khē or Keheh, is a letter of Arabic script, used to write /kʰ/ in Sindhi. It is equivalent to क in Sindhi's Devanagari orthography.In Arabic, it is considered a variant form of kāf, notably al-kāf al-mashkūlah or al-kāf al-mashqūqah. It is the predominant form of kāf in the Perso-Arabic script.
But in Sindhi, khē and kāf are differentiated: khē (ک‎) is used consistently for /kʰ/, and kāf (ڪ‎) for /k/. This is similar to the history of I and J, and of U and V, in the Latin alphabet.
