Once I disambiguated the various quotation marks, assigned them to the 
preferred XeTeXcharclass in my .tex file, and stopped trying to rewrite 
zhspacing, I got the desired results. To disambiguate the quotation 
marks themselves, I found this explanation useful:
<http://www.unicode.org/versions/Unicode5.0.0/ch06.pdf#G8392>

And I'm looking at the explanations of 'class' in The TeXbook, p154 ff.

Now I'm trying to figure out why the enclosed number characters, e.g. ① 
, show as a blank in the PDF.
E.g.,【泰】水-5-10 tài  >〈形〉①順適如意﹑命運亨通。

"\XeTeXcharclass`①=6" by itself doesn't seem to work. More study is needed.

This works fine. Thank you.

Dealing with CJK fonts with XeTeX and fontspec has been a pleasure.

Thank you, YIN Dian [音點/飲店/陰電 ?? <g>],  for answering my other two 
questions.

At the end of the day, perhaps there should be a way to automatically 
switch fonts based on the encoding range containing the underlying 
Unicode characters, an expanded and more rigorous implementation of what 
is done in OpenOffice Writer, for example, where in Preferences the 
fonts for "Western" and "Asian" can be set.

Once again, thanks for your help.
