GH-25: HTML 4 browsers don't support ' entity

See https://stackoverflow.com/a/2083770 which refers to this spec: C.16. The Named Character Reference ' https://www.w3.org/TR/xhtml1/#C_16 The named character reference ' (the apostrophe, U+0027) was introduced in XML 1.0 but does not appear in HTML. Authors should therefore use ' instead of ' to work as expected in HTML 4 user agents.
