non-apostrophe apostrophes (and similar non-ascii quotes)

We have a mixture of ' and ’ in our support entries.

This produces surprising behavior -- for example the recent !174 (closed) diff shows

-title: I can’t connect to Tor Browser. Is my network censored?
+title: I can’t connect to Tor with Tor Browser, is my network censored?

which probably isn't what anybody expected to see in a diff.

I assume the ’ snuck in via a paste from google docs or microsoft word or the like.

We should unify on one, and imo it should be the actual ascii apostrophe character (decimal 39).

I also wonder what the translations have done with this mixed-apostrophe situation.

We also have similar issues in the tb-manual, including mixed non-ascii quotes in adjacent sentences, e.g.: Users who require a high degree of security in their web browsing should set Tor Browser’s [Security Level](../security-settings/) to “Safer” (which disables JavaScript for non-HTTPS websites) or “Safest” (which does so for all websites). However, disabling JavaScript will prevent many websites from displaying correctly, so Tor Browser’s default setting is to allow all websites to run scripts in "Standard" mode.
