+Summary: Marshaling a Unicode StringBuilder does not work
+
+Marshalling StringBuilder as Unicode parameter does not work. It works for
+ANSI calls but not for Unicode. Platform Windows XP SP1.
+
+Running the attached example under Microsoft .Net 1.1 produces the
+following output:
+
+Font Family Handle->116098752
+C
+o
+u
+r
+i
+e
+r
+
+N
+e
+w
+FontFamily->Ok - Courier New
+
+The same example under Mono HEAD produces:
+
+Font Family Handle->26117824
+C
+FontFamily->Ok - C
+
+It seems that the string is marshalled as an ANSI string. The API call that
+is not properly marshaled is:
+
+[DllImport ("gdiplus.dll", CharSet=CharSet.Unicode)]
+internal static extern Status GdipGetFamilyName(IntPtr family,
+StringBuilder fName, int language);
