Doire is a monowidth font based on the face used on the old Royal Gaelic manual typewriter. Doire Royal is a “rough” version of that font.

Doire was first digitized in 1993 by Michael Everson and originally used the MacGaelic character set on the Macintosh platform, and ISO/IEC 9958-14 on the PC. In 2008 Doire version 3 was released in OpenType format, completely compliant with Unicode encoding and with an extended character set.
