ISO-639 mga (Middle Irish) and ghc (Hiberno-Scottish Gaelic)

[silmeth]

Those codes are not associated with any language system.

mga is ISO-639-2 code for Middle Irish (Gaelic dialects of ~900–1200, the stage after Old Irish – sharing its written tradition, some Old Irish texts being preserved in Middle Irish manuscripts), ghc is an ISO-639-3 code for “Hiberno-Scottish Gaelic” which is a name given by Ethnologue to Classical Gaelic or Classical Irish – the standardized language of Gaelic poetry of ~1200–1750.¹

So it would make sense to me to:

• add mga to SGA (Old Irish) Language System Tag,
• add ghc to IRT (Irish Traditional) system,
• or add separate Language Systems for those stages of Irish/Gaelic.

Lack of association for those codes causes texts using the insular (“Gaelic”) type in HTML elements marked with lang="mga" or lang="ghc" to render incorrectly using Junicode 2 font, see psb1558/Junicode-font#170
