Mac OS Romanis acharacter encodingcreated byApple Computer, Inc.for use byMacintoshcomputers.[1]It is suitable for representing text inEnglishand several other languages that use the Latin script. Mac OS Roman encodes 256 characters, the first 128 of which are identical toASCII,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 only 217 characters.[1]Full support for Mac OS Roman first appeared inSystem 6.0.4,released in 1989,[2]and the encoding is still supported in current versions ofmacOS,though the standard character encoding is nowUTF-8.Apple modified Mac OS Roman in 1998 with the release ofMac OS 8.5by replacing thecurrency signwith theeuro sign,[3]but otherwise the encoding has been unchanged since its release.
