Many of these characters were originally intended for use as bullets for lists.
[''The Unicode Standard'', 6.0.1] The parenthesized forms are historically based on typewriter approximations of the circled versions.
Although these roles have been supplanted by styles and other markup in "rich text" contexts, the characters are included in the Unicode standard "for interoperability with the legacy East Asian character sets and for the occasional text context where such symbols otherwise occur."
The Unicode Standard considers these characters to be distinct from characters which are similar in form but specialized in purpose, such as the
circled C,
P or
R characters which are defined as copyright and trademark symbols or the
circled a used for an at sign.
