Apple's corporate character sets have several cases where one
character maps to multiple Unicode characters. For example, MacKorean
has a separate codepoint for circled numerals not included in Unicode.

Since these are corporate character sets (and not national or
international standards), and since Apple itself felt that the
multiple-Unicode mapping was perfectly acceptable, there was never any
need felt to have one-to-one mapping.
