Uddin and Begum Hindustani Romanisation
The Uddin and Begum Hindustani Romanisation scheme is an international standard for romanising (transliterating into the Latin alphabet) Urdu and Hindi (sometimes jointly referred to as the Hindustani language, particularly in the era of British India). Syed Fasih Uddin and Quader Unissa Begum presented the scheme in 1992, at the First International Urdu Conference in Chicago.
