Editing Roman numerals (section)

==Unicode==
The "[[Number Forms]]" block of the [[Unicode]] computer character set standard has a number of [[Numerals in Unicode#Roman numerals|Roman numeral symbols]] in the range of [[Unicode code point|code points]] from U+2160 to U+2188.<ref name="UnicodeChartU2150">{{Cite web |url=https://www.unicode.org/charts/PDF/U2150.pdf |title=Unicode Number Forms}}</ref> This range includes both upper- and lowercase numerals, as well as pre-combined characters for numbers up to 12 (Ⅻ or {{rn|XII}}). One justification for the existence of pre-combined numbers is to facilitate the setting of multiple-letter numbers (such as VIII) on a single horizontal line in Asian vertical text. The Unicode standard, however, includes special Roman numeral code points for compatibility only, stating that "[f]or most purposes, it is preferable to compose the Roman numerals from sequences of the appropriate Latin letters".<ref>{{Cite web |date=2011 |title=The Unicode Standard, Version 6.0 – Electronic edition |url=https://www.unicode.org/versions/Unicode6.0.0/ch15.pdf |publisher=Unicode, Inc. |pages=486}}</ref> The block also includes some {{lang|la|apostrophus}} symbols for large numbers, an old variant of "{{rn|L}}" (50) similar to the Etruscan character, the [[Claudian letter]] "reversed C", etc.<ref>{{Cite web |title=Roman symbol |url=https://symbolonly.com/roman-symbols.html |website=symbolonly.com}}</ref>
