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. --J"org Knappen
