+.IP "\fBpterm.WideFont\fP"
+This resource is the same as the \fI\-fw\fP command-line option: it
+controls the font used to display double-width characters. The
+default is unset (double-width characters cannot be displayed).
+.IP "\fBpterm.WideBoldFont\fP"
+This resource is the same as the \fI\-fwb\fP command-line option: it
+controls the font used to display double-width characters in bold,
+when \fIBoldAsColour\fP is turned off. The default is unset
+(double-width characters are displayed in bold by printing them
+twice at a one-pixel offset).
+.IP "\fBpterm.ShadowBoldOffset\fP"
+This resource can be set to an integer; the default is \-1. It
+specifies the offset at which text is overprinted when using "shadow
+bold" mode. The default (1) means that the text will be printed in
+the normal place, and also one character to the right; this seems to
+work well for most X bitmap fonts, which have a blank line of pixels
+down the right-hand side. For some fonts, you may need to set this to
+\-1, so that the text is overprinted one pixel to the left; for
+really large fonts, you may want to set it higher than 1 (in one
+direction or the other).
