We'll create fresh WordPress site with Smart Quotes installed. You have 20 minutes to test the plugin after that site we'll be deleted.
Change the quotation marks, that are automatically rendered as smart or curly quotes inside your content, from the default English style (“…”) to anything you like, e.g. to Croatian/Hungarian/Polish/Romanian style quotation marks („…”), Czech or German style („…“), Danish style (»…«), Finnish or Swedish style (”…”), French style (« … » – with spaces), Greek/Italian/Norwegian/Portuguese/Russian/Spanish/Swiss style («…» – without spaces), Japanese or Traditional Chinese style (「⋯」), or actually to any arbitrary character combination of your choice. Of course you can turn off curly quotes entirely by picking the so-called "dumb" quotes ("…").
