+formatters convert the following ASCII input characters to the
+following Unicode special output characters:
+.Bl -column x(ga U+2018 -offset indent
+.It \(ga Ta U+2018 Ta left single quotation mark
+.It \(aq Ta U+2019 Ta right single quotation mark

+In prose, this automatic substitution is often desirable;
+but when these characters have to be displayed as plain ASCII
+characters, for example in source code samples, they require
+escaping to render as follows:
+.Bl -column x(ga U+2018 -offset indent
+.It \e(ga Ta U+0060 Ta grave accent
+.It \e(aq Ta U+0027 Ta apostrophe
+.It \e(ti Ta U+007E Ta tilde
