Orthography
The orthography was standardized in 1983-84 and used from 1985 onward. It's based on the Sindhi alphabet with three additional letters: ۮ, representing a voiced dental implosive, ۯ, representing a retroflex lateral approximant, and ۿ, representing a voiced glottal fricative. These letters all use an inverted V as the diacritical mark because Sindhi already makes frequent use of dots. Before sindhi typing was to put just dots and now it is much modernized than before.
