The {{' " '}} (or{{Single+double+single}} in long form) template is for use a) at the beginning of a 'single-quoted' quotation that begins a "double-quoted" quotation that in turn begins an enclosing 'single-quoted' quotation, or b) at the end of a 'single-quoted' quotation that ends a "double-quoted" quotation that in turn ends an enclosing 'single-quoted' quotation. Its purpose is to slightly space the single and double quotation marks apart for legibility, without actually inserting a space character. It does this with CSS, and does so because the insertion of extraneous space characters of any kind would be a violation of the semantic integrity of the web content of the article or other page in which it appeared.
