22189	"""wikipedia tag has an unknown language prefix"" in Belarus"	anonymous	team	"Hi, 

I don't have OSM so I can't create the ticket from there. But there's no need I think, it's not a JOSM problem but a validator one. The validator (used by OSMOSE as well) flagged 1267 tags in Belarus, such as: ""wikipedia=be-tarask:Лунін"", but be-tarask is a valid wikipedia prefix: https://be-tarask.wikipedia.org/

Another Wikipedia problem that could be fixed: https://josm.openstreetmap.de/ticket/21802
Georgian doesn't have capitalized letters."	defect	new	normal		Core
