Unicode Devanagari अ
In india, you have over a hundred different langs. They can be grouped roughly into 2 families: Indo-Aryan and Dravidian.
The most popular language of the Indo-Aryan family is Hindi, and Hindi uses Devanagari as its writing system.
In 1950, India gov decided Hindi is “official” and English too but can be phased out in 15 years. That never happened, and it turns out, many parts of india (especially southern) resist against that, because, Hindi is entirely diff lang than their native langs.
Devanagari (/ˌdeɪvəˈnɑːɡəri/ DAY-və-NAH-gər-ee; देवनागरी, IAST: Devanāgarī, Hindi pronunciation: [deːʋəˈnaːɡəri]), also called Nagari (Nāgarī, नागरी), is a left-to-right abugida (alphasyllabary), based on the ancient Brāhmī script, used in the Indian subcontinent. It was developed in ancient India from the 1st to the 4th century CE, and was in regular use by the 7th century CE. The Devanagari script, composed of 47 primary characters including 14 vowels and 33 consonants, is one of the most adopted writing systems in the world, being used for over 120 languages. The ancient Nagari script for Sanskrit had two additional consonantal characters.
Among the languages using it – as either their only script or one of their scripts – are Hindi, Sanskrit, Pali, Awadhi, Bhojpuri, Braj Bhasha, Chhattisgarhi, Haryanvi, Magahi, Nagpuri, Rajasthani, Bhili, Dogri, Marathi, Nepali, Maithili, Kashmiri, Konkani, Sindhi, Bodo, Nepalbhasa, Mundari and Santali. The Devanagari script is closely related to the Nandinagari script commonly found in numerous ancient manuscripts of South India, and it is distantly related to a number of southeast Asian scripts.
