U2170U217F

U+2170 to U+217F define the Small Roman Numerals block in the Unicode Standard. This block provides lowercase forms of the common Roman numeral symbols, offering a typographic option when lowercase numerals are required in running text or specialized formats. The range contains 16 code points that correspond to the canonical numeral values used in Roman notation: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 50, 100, 500, and 1000. In practical terms, these are single-character glyphs such as ⅰ (U+2170) for 1 and ⅹ (U+2179) for 10, along with lowercase forms for the other standard values (including the lowercase representations of 50, 100, 500, and 1000) as defined by the block.

Relation to other blocks: The Small Roman Numerals block complements the Uppercase Roman Numerals block, which occupies U+2160 to U+216F. Together, these blocks provide both uppercase and lowercase single-symbol representations for key Roman numeral values, enabling consistent typographic usage across different languages and styles.

Usage and typography: These characters are primarily used for stylistic purposes in publications, headings, outlines, emblems, or historical texts where a lowercase Roman numeral aesthetic is desired. They are not commonly required in everyday writing, but they remain part of the Unicode repertoire to support precise typography and compatibility across systems.

Technical notes: Support for the Small Roman Numerals varies by font and platform. Most modern fonts that include the Unicode Roman numeral range will display these glyphs, but rendering can depend on font coverage and fallback behavior in a given application or operating system.
