I see a precedent in Unicode to treat Copyright-like sign differently from
simple encircled letters:
Unicode takes precautions not to encode the same character twice.
Therefore, superscript digits 2 and 3 are absent from the superscript
block U+2070 ff.
However, the Block eclosed alphanumerics U+2460 ff includes encircled
capital latin letters C, P, and R in addition to the copyright-like sing
elsewhere.
