thanks, I find some documentations about the method.

(GDI+ DrawDriverString doesn't handle underlined or stroken out fonts as expected): we had to implement this by hand
If anyone wants to draw text using Gdiplus(GDI+) with font styles (including
strikeout and underline), please use DrawString() instead of
DrawDriverString() because the latter does'nt seems to support underlining &
striking of font characters though the font is properly loaded(displays empty
spaces in place of underlined and striked out chars), but the former supports
all FontStyles.
