About this character

U+2173 (ⅳ) is SMALL ROMAN NUMERAL FOUR, a letterlike number in the Number Forms block. It belongs to the Latin script. It was added in Unicode 1.1 (1993).

Its uppercase form is U+2163 Ⅳ.

It is a compatibility variant of U+0069 i + U+0076 v (compatibility decomposition <compat>). NFC and NFD leave it alone, but NFKC and NFKD replace it with U+0069 i + U+0076 v. Search engines, identifier checks and username systems that apply NFKC will treat the two as the same text.

It has the numeric value 4.

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.
