Maybe that Emacs user from China could also suggest a patch for Emacs
to fix this issue?

Po Lu, any comments or suggestions?

The Vim code uses ImmSetCompositionFont function to set the font.  I
don't have a good idea how to choose a font for that function, but
perhaps we could use ImmGetCompositionFont to retrieve the font used
by default, and then change its height and call ImmSetCompositionFont?

I'm just stabbing in the dark, and I don't have a way of testing these
ideas anyway.
