About this character

U+2139 (ℹ) is INFORMATION SOURCE, a lowercase letter in the Letterlike Symbols block. Its script is Common: it is shared by many writing systems rather than belonging to one. It was added in Unicode 3.0 (1999).

Its emoji name (CLDR short name) is “information”, in the Symbols group, subgroup alphanum. By default it is shown as a text glyph; follow it with U+FE0F VARIATION SELECTOR-16 to request the colour emoji form (U+2139 U+FE0F), or with U+FE0E VARIATION SELECTOR-15 to force text style.

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