+.IP "\fB\-cs\fP \fIcharset\fP"
+This option specifies the character set in which \fIpterm\fP should
+assume the session is operating. This character set will be used to
+interpret all the data received from the session, and all input you
+type or paste into \fIpterm\fP will be converted into this character
+set before being sent to the session.
+
+Any character set name which is valid in a MIME header (and
+supported by \fIpterm\fP) should be valid here (examples are
+"ISO-8859-1", "windows-1252" or "UTF-8"). Also, any character
+encoding which is valid in an X logical font description should be
+valid ("ibm-cp437", for example).
+
+\fIpterm\fP's default behaviour is to use the same character
+encoding as its primary font. If you supply a Unicode (iso10646-1)
+font, it will default to the UTF-8 character set.
+
+Character set names are case-insensitive.
