Fractions in a single character
Precomposed fractions like ½, ¼ and ¾ look tidier than slashes in recipes, measurements and price lists. Unicode covers halves, thirds, quarters, fifths, sixths and eighths, along with ⅐, ⅑ and ⅒ for sevenths, ninths and tenths. For anything else, combine superscript and subscript digits with the fraction slash ⁄ to build your own, such as ⁵⁄₁₂ or ¹¹⁄₁₆.
Circled numbers and Roman numerals
Circled numbers ① to ⑳ make neat step markers in instructions, rankings and slides, and the filled ❶ style stands out even more. Roman numerals Ⅰ to Ⅻ are popular for chapter headings, clock faces and event names. Note that each numeral, like Ⅻ, is a single character here, so it keeps its shape but may not be found when someone searches for the letters XII.
