Template:Short description Template:Distinguish Template:Infobox character encoding Mac OS Roman is a character encoding created by Apple Computer, Inc. for use by Macintosh computers.<ref name="im-text1">Template:Cite book</ref> It is suitable for representing text in 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, diacritics, 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 6.0.4, released in 1989,<ref name="im-vi">Template:Cite book</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 8.5 by replacing the currency sign with the euro sign,<ref name="tn1140">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> but otherwise the encoding has been unchanged since its release.
