--
-- This implements several useful functions for dealing with D'ni text in the Wiki.
--
-- parsed_dni() returns a string in which every component is linked to its appropriate Dictionary namespace entry.
-- dnifont2ots() converts a Dnifont string to an ots one
-- dnifont2nts() converts a Dnifont string to an nts one
