From that same page:


PangoFontDescription * pango_font_description_from_string
                                                        (const char *str);

Creates a new font description from a string representation in the form 
"[FAMILY-LIST] [STYLE-OPTIONS] [SIZE]", where FAMILY-LIST is a comma separated 
list of families optionally terminated by a comma,
                           ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^


pango_font_description_to_string ()

char *              pango_font_description_to_string    (const 
PangoFontDescription *desc);

Creates a string representation of a font description. See 
pango_font_description_from_string() for a description of the format of the 
string representation. The family list in the string description will only 
have a terminating comma if the last word of the list is a valid style option.
