Mac OS Celtic is a character encoding used by the 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.

Notes

  • ^⌘ The (usually nonprintable) character 0x11 mapped to the Command key glyph (⌘) in many fonts, particularly those intended for use as system fonts. It is mappable to the Unicode character U+2318 ⌘ PLACE OF INTEREST SIGN. The codes 0x12, 0x13, and 0x14 were also used for icons to indicate the shift, option, and control keys in menu items.
  • ^* The codes 0xA2, 0xA3, 0xA9, 0xB1, and 0xB5 coincidentally have the same character assignment as ISO 8859-1 (and thus Unicode).
  • ^¤ Before Mac OS 8.5, the character 0xDB mapped to currency sign (¤), Unicode character U+00A4.
  • ^a The character 0xF0 is a solid Apple logo. The Unicode equivalent U+F8FF is in the Corporate Private Use Area, but it is probably not supported on non-Apple platforms.
