Mac OS Celtic is a character encoding used by Mac OS to represent Welsh text (like ISO 8859-14), replacing 14 of the Mac OS Roman characters with Welsh characters. This character set was developed by Michael Everson and was used for the Irish localizations of Mac OS 6.0.8 and 7.1 and for the Welsh localization of Mac OS 7.1.

ISO/IEC 8859-11:2001, Information technology — 8-bit single-byte coded graphic character sets — Part 11: Latin/Thai alphabet, is part of the ISO/IEC 8859 series of ASCII-based standard character encodings, first edition published in 2001. It is informally referred to as Latin/Thai. It is nearly identical to the national Thai standard TIS-620 (1990). The sole difference is that ISO/IEC 8859-11 allocates non-breaking space to code 0xA0, while TIS-620 leaves it undefined.

ISO/IEC 8859-14:1998, Information technology — 8-bit single-byte coded graphic character sets — Part 14: Latin alphabet No. 8 (Celtic), is part of the ISO/IEC 8859 series of ASCII-based standard character encodings, first edition published in 1998. It is informally referred to as Latin-8 or Celtic. It was designed to cover the Celtic languages, such as Irish, Manx, Scottish Gaelic, Welsh, Cornish, and Breton.

Mac OS Roman is a character encoding created by Apple Computer, Inc. for use by Macintosh computers. It is suitable for representing text in English and several other Western languages. 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 only 217 characters. Full support for Mac OS Roman first appeared in System 6.0.4, released in 1989, and the encoding is still supported in current versions of macOS, though the standard character encodings are now UTF-8 or UTF-16. Apple modified Mac OS Roman in 1998 with the release of Mac OS 8.5 by replacing the currency sign at position hexadecimal 0xDB with the euro sign, but otherwise the encoding has been unchanged since its release.
