I thought that (') was the apostrophe character, although it doesn't look like one. (Source: http://www.cl.cam.ac.uk/~mgk25/ucs/apostrophe.html) The same source agrees with you elsewhere though, making my distinction pedantic. (http://www.cl.cam.ac.uk/~mgk25/ucs/quotes.html)

I can't personally imagine this solution would be any less confusing, given that the new preferred apostrophe character according to this source is specifically a right single quote character.
