I ran into this same issue.  I think the fontconfig manual describes
only what fontconfig itself uses in its configuration files. 
No application program I have tried recognizes font names given in
that form.

   set term pdfcairo font "Bitstream Charter Bold"
   set term pdfcairo font "Bitstream Charter Bold Italic"

This is a relatively recent addition to the pdfcairo terminal
(7 May 2008).  Spaces and hyphens are treated as equivalent,
which allows you also to use names from the standard PostScript
font set like "Times-Italic" and "Helvetic-Bold".
