“Smart quotes,” the correct quotation marks and apostrophes, are curly or sloped. "Dumb quotes," or straight quotes, are a vestigial constraint from typewriters when using one key for two different marks helped save space on a keyboard. Unfortunately, many improper marks make their way onto websites because of dumb defaults in applications and CMSs. Luckily, using correct quotation marks and apostrophes today is easier than you think. The simplest method is to use charset utf-8 on your webpages and just type or copy and paste the actual punctuation marks.
