This character is a Other Punctuation and is commonly used, that is, in no specific script. It is also used in the scripts Bopomofo, Hangul, Han, Hiragana, Katakana, Yi.

The CLDR project calls this character “katakana middle dot” for use in screen reading software. It assigns these additional labels, e.g. for search in emoji pickers: dots, interpunct, katakana, middot.

The Wikipedia has the following information about this codepoint:

An interpunct ⟨·⟩, also known as an interpoint, middle dot, middot, centered dot or centred dot, is a punctuation mark consisting of a vertically centered dot used for interword separation in Classical Latin. (Word-separating spaces did not appear until some time between 600 and 800 CE.) It appears in a variety of uses in some modern languages and is present in Unicode as U+00B7 · MIDDLE DOT.

The multiplication dot (Unicode U+22C5 ⋅ DOT OPERATOR) is frequently used in mathematical and scientific notation, and it may differ in appearance from the interpunct.
