Unicode Number Forms are encoded solely for compatibility with existing standards.

The vulgar fraction characters can be equivalently represented using U+2044    fraction slash ⁄.

The Roman numerals can be composed of sequences of the appropriate Latin letters. Majuscule and minuscule variants of the Roman numerals through 12, plus L, C, D and M have been encoded for compatibility with East Asian standards.

U+2180    Roman numeral one thousand C D and U+216f    Roman numeral one thousand
can be considered glyphic variants of the same Roman numeral, but are distinguished because they are not generally interchangeable, and because U+2180 cannot be considered a compatibility equivalent to the Latin letter M.

U+2183    Roman numeral reversed one hundred is a form used in combinations with C and/or I to form large numbers, some of which vary with single character number forms such as D, M, U+2181 and others.


Unicode's Number Forms code block reserves the 64 code points from U+2150 to U+218F, of which 54 are currently assigned.
