Prime sign (’) is less compatible than single quote (')

[yuchsiao]

Although the prime sign (’), for example, "Man’s" as opposed to "Man's" , is semantically more accurate than single quote ('), in many cases, single quotes are easier to handle when it comes to ASCII code system (even in Excel on MAC). So it would be easier to use your great efforts if all the primes are replaced by single quotes.
