{You do that simple by converting it to an integer, and then stores that:}

 type
   pFontStyles = ^TFontStyles;
   pInteger = ^integer;

 function FontStylesToInteger(const Value : TFontStyles): integer;
 begin
   Result := pInteger(@Value)^;
 end;

 function IntegerToFontStyles(const Value : integer): TFontStyles;
 begin
   Result := pFontStyles(@Value)^;
 end;
