The character shown in the .png (U+60CA) has a contour of width 0,
namely all points have same x value (bug?), in the left top corner.
It misleads FT_Outline_Get_Orientation.  Thus instead of emboldened,
each stroke got shrinked.

Similar issues have already been seen in some free traditional Chinese
fonts.  They have glyphs consisting of components of different
orientations.  I think it's a bug of the font and since those fonts are
actively maintained, I reported the issue to the font authors, after
failed to work around this in freetype.
