-- Note: 
-- It seems that objects/lists stored via luacache have a limit on the number of entities,  which is about 8k.
-- Any object/list which has more then 8k entities or having such a large sub-object/sub-list will be truncated.
-- Therefore, we encode the data into a string to get around this problem.

	load = function(lang)

			-- This cache can be purged by:
			-- * purge Module:tr/db-<lang> or Module:tr/db-<lang>/doc page
			-- * lua code: require('Module:Tr/loaddata').purge(<lang>)
			-- * template code: {{#invoke:tr|purge|lang=<lang>}}
