Smart Apostrophe
Updated:
Smart apostrophes/curved quotes are… interesting. There are over 30 characters that are considered quotation marks in Unicode. The most well-known are the quotation mark (“, \") and apostrophe (‘, \'). These are the characters available in ASCII.
Word Processors
Word processors have been transforming the quotation mark into their respective stylized unicode characters for presentation. For example, when you wrap a word with quotes, most word processors will do all the smarts necessary to determine that you intend to surround with open and close quotes, respectively. As a user, I appreciate that I don’t have to differentiate, as the use case is consistent and it seems unnecessarily pedantic to require the user to do so manually. But I can see why typographers would be less than ecstatic about magic handling or misconceptions resulting not understanding these are distinct characters.
Applescript
This bit me when writing a script in Applescript. Applescript uses curly quotes for string literals. It makes the least amount of sense, even typographers would probably agree that this is not the starting place they would choose, for a hill to die on. It’s literally for the scripting language, it doesn’t even need to be smart quotes. We just need delimiters for string literals and, by convention, we chose double quotes.
