Mac OS Celtic

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.

Layout
The table below shows the second half of the encoding, the first half (codes 0–127) being ASCII.
