+.Ss Character Escapes
+This section documents the character-escapes accepted by
+.Xr mdocterm 1 .
+Note that the \\x, \\(xx and \\[n] forms are described here; the \\*(xx
+and \\*x forms described in
+.Xr mdoc.samples 7
+are deprecated, but still correctly rendered.  For all two-character
+sequences, \\(xx is equivalent to the n-character \\[xx].
+.Pp
+Note that the
+.Em Output
+column will render differently whether executed with
+.Xr mdocterm 1 
+or another output filter.
