This template applies custom styling (better typefaces and/or typefaces that support uncommon scripts and/or bigger size text) to scripts (writing systems), identified by their ISO 15924 alpha-4 code. It takes two unnamed parameters: the ISO code, and the text to transform. Some scripts can also be identified by their name.
This template does not mark up text as being X language. For instance, Hebrew text marked up using ((Script/Hebrew)) will be marked up as Hebrew script, but not Hebrew text.
This means that foreign-language text will not be invisibly marked up as a different language in the same manner as ((lang)) or ((transl)). Non-English text needs to be marked up in ((Language templates)) for accessibility; see MOS:OTHERLANG for more details.
