About this character

U+2081 (₁) is SUBSCRIPT ONE, a numeric character in the Superscripts and Subscripts block. Its script is Common: it is shared by many writing systems rather than belonging to one. It was added in Unicode 1.1 (1993).

It is a subscript form of U+0031 1 (compatibility decomposition <sub>). NFC and NFD leave it alone, but NFKC and NFKD replace it with U+0031 1. Search engines, identifier checks and username systems that apply NFKC will treat the two as the same text.

It has the numeric value 1.

Its East Asian Width is Ambiguous: it takes one column in Western contexts and two in East Asian legacy contexts, a common cause of misaligned tables in terminals.
