...to "Find functions that take rtl::O[U]String parameters that can be generalized to take std::[u16]string_view instead." (Which in turn can avoid costly O[U]String constructions, see e.g. loplugin:stringview and subView.) Some of those functions' call sites, passing plain char string literals, needed to be adapted when converting them.
