Werner and Toshiya-san,
I put the font as a tricky font to deal
with.
static const char trick_names[TRICK_NAMES_COUNT]
[TRICK_NAMES_MAX_CHARACTERS + 1] =
{
"DFKaiSho-SB", /* dfkaisb.ttf */
"DFKaiShu",
"DFKai-SB", /* kaiu.ttf */
"HuaTianKaiTi?", /* htkt2.ttf */
"HuaTianSongTi?", /* htst3.ttf */
"MingLiU", /* mingliu.ttf & mingliu.ttc */
"PMingLiU", /* mingliu.ttc */
"MingLi43", /* mingli.ttf */
"BKLGIB+FA"
---------------------------------------- this is the embeded font in th
document.
};
it still render error. 
.
.I opened the embeded font use font lab, found the gid =
2134 is like this, please see the attach bitmap,
some of lines form a 0 area areas, then fill the
area(have no area), Does freetype made special
processing?

No, the FreeType *library* must be built with it: Edit ftoption.h to
set this flag, then recompile.
Additionally, hinting must be enabled for this font, this is,
FT_LOAD_NO_SCALE doesn't work here.
Normally, those steps are (more or less) handled automatically by
FreeType, since we maintain a list of `tricky' font like the one you
have encountered in the PDF; see file `ttobjs.c'. The subsetted font
in question, however, which identifies itself as
BKLGIB+FA-RoundGothicB
ＦＡ 丸ゴシックＢ and FA-RoundGothicB are trademarks of NEC Office Systems,Ltd.
isn't in this list; for the NEC FA fonts (and others), a second
mechanism is used which doesn't work with subsetted fonts.
Toshiya-san, any ideas?
Werner
