I can understand your points now. Indeed, we guys using XeTeX
to typeset Chinese are not very satified with glue between CJK
characters and Latin characters. So the questions is, can we solve
this problem at TeX macro level? If not, we still need low level
mechanism provided by some XeTeX primitives.
