Description Eike Rathke 2022-08-11 09:38:38 UTC

The character attribution's Font Language edit field accepts valid BCP 47 language tags to be added, except x-... private-use tags, on purpose to prevent spreading misassignments. It should allow adding language tags for artificial constructed languages though with tags art-x-... and art-Latn-x-... (with Latn being any valid script code) so these could be used without the kludge of having to create and edit the stored source of a document (see https://ask.libreoffice.org/t/how-to-create-an-exportable-keyboard-input-scheme/80482/4 )
