U+2064 "⁤" Invisible Plus Unicode Character

U+2064 "⁤" Invisible Plus is a formatting character that, as its name suggests, represents an invisible mathematical plus sign, intended to indicate addition in contexts where a visible symbol might be disruptive or unwanted, such as in algebraic or typographical layouts where the plus operation is implied. It belongs to the General Punctuation block and has no visible glyph, serving purely as a semantic marker for software processing or specialized text rendering, though its practical usage remains extremely limited and it is not widely supported across common applications or fonts.
