A preliminary proposal to encode the 'Prachalit Nepal' script (प्रचलित नेपाल लिपि) in Unicode has been submitted. The Prachalit Nepal script is the name by which the 'Newari' script is presently promoted. Although 'Newari' has been used in Nepali and Western languages in reference to the Newar community, language, and script, the term is not used by the Newar community.

Research on the script is ongoing. A formal proposal will be developed in collaboration with users of Prachalit Nepal script. I welcome any information or comments!
