Problem when use small-caps and the underline with bold attributes in the XSL-FO

Hi,

When I'm using small-caps and the underline with bold attributes in the XSL-FO, it produces the small jerk in the first letter of the string in the PDF output.

Eg. <fo:block font-variant="small-caps" font-weight="bold" text-decoration="underline">World</fo:block>

In output of the above line will have jerk in the "W" in the underline.

How to resolve this.

Rgds,
Soma
