'''Mac OS Roman''' is a [[character encoding]] created by [[Apple Inc.|Apple Computer, Inc.]] for use by [[Macintosh]] computers.<ref name="im-text1">{{cite book|last=Apple Computer, Inc. |title=Inside Macintosh: Text |date=1993  |url=https://developer.apple.com/library/archive/documentation/mac/pdf/Text.pdf#page=88 |url-status=live |access-date=July 10, 2021 |page=1-53 |publisher=Addison Wesley Publishing Company |isbn=0-201-63298-5|archive-url=https://web.archive.org/web/20191211055829/https://developer.apple.com/library/archive/documentation/mac/pdf/Text.pdf#page=88 |archive-date=2019-12-11}}</ref> It is suitable for representing text in [[English language|English]] and several other languages that use the Latin script. Mac OS Roman encodes 256 characters, the first 128 of which are identical to [[ASCII]], with the remaining characters including mathematical symbols, [[diacritic]]s, and additional punctuation marks. Mac OS Roman is an extension of the original Macintosh character set, which encoded 217 characters.<ref name="im-text1" /> Full support for Mac OS Roman first appeared in [[System 6|System 6.0.4]], released in 1989,<ref name="im-vi">{{cite book|last=Apple Computer, Inc. |title=Inside Macintosh, Volume VI |date=1991 |page=14-104 |isbn=0-201-57755-0}}</ref> and the encoding is still supported in current versions of [[macOS]], though the standard character encoding is now [[UTF-8]]. Apple modified Mac OS Roman in 1998 with the release of [[Mac OS 8|Mac OS 8.5]] by replacing the [[Currency sign (generic)|currency sign]] with the [[euro sign]],<ref name="tn1140">{{cite web|last=Apple Computer, Inc. |title=Technical Note TN1104: The Euro Currency Symbol |date=September 14, 1998  |url=https://developer.apple.com/library/archive/technotes/tn/tn1140.html |access-date=July 10, 2021}}</ref> but otherwise the encoding has been unchanged since its release.
