Which direction is an apostrophe?

Solution 1:

This could just about be about English, since other languages have other forms of apostrophe, but a simple Google search provides the answer.

Here's an excerpt from the first results of a Google Books search for people's:

(Conservation and Mobile Indigenous Peoples, Chatty & Colchester, Berghahn 2002)

However, even typing people’s in Windows, using Alt0146 for the apostrophe, provides a result, which could also be seen by looking online for examples.

Other “printers’ quotes” follow the 6–9 rule: six comes before nine, and opening quotes look like 6 with closing quotes looking like 9. Since an apostrophe is a closing quote (see printers’) it's a 9.
