And to complete the answer for Thomas, the Roman numerals are
based on Latin letters, which *do* have upper/lowercase distinctions,
unlike digits. The compatibility Roman numerals in the Unicode
Standard (U+2160..U+217F) are derived from East Asian standards
which separately encoded upper- and lowercase forms, so would have
been required to be separately encoded just for compatibility
