The Wikipedia has the following information about this codepoint:

The double hyphen (=, ゠, or ⸗) is a punctuation mark that consists of two parallel hyphens. It is not to be confused with two consecutive hyphens (--), which are often used to represent an em dash (—) or en dash (–). (This practice arose due to the limitations of typewriter character sets which did not have both hyphen and dash.) In order to avoid its being confused with the equals sign (=), the double hyphen is often angled slightly.
