Feature: #103255 - Native support for language Scottish Gaelic added

See forge#103255

Description

TYPO3 now supports Scottish Gaelic. Scottish Gaelic language is spoken in Scotland.

The ISO 639-1 code for Scottish Gaelic is "gd", which is how TYPO3 accesses the language internally.

Impact

It is now possible to

  • Fetch translated labels from translations.typo3.org / CrowdIn automatically within the TYPO3 backend.
  • Switch the backend interface to Scottish Gaelic language.
  • Create a new language in a site configuration using Scottish Gaelic.
  • Create translation files with the "gd" prefix (such as gd.locallang.xlf) to create your own labels.

TYPO3 will pick Scottish Gaelic as a language just like any other supported language.
