Mac OS Roman is a character encoding created by Apple Computer, Inc. for use by Macintosh computers.^[1] 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.^[1] Full support for Mac OS Roman first appeared in System 6.0.4, released in 1989,^[2] 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,^[3] but otherwise the encoding has been unchanged since its release.

The following table shows how characters are encoded in Mac OS Roman. The row and column headings give the first and second digit of the hexadecimal code for each character in the table.
