I think show-trailing-whitespace should not be affected by
syntax of characters because what it should concern is a
glyph.  If a glyph of a character is just space, even if the
syntax is `symbol' or whatever else, it should be
highlighted.

So, what we need is a char-table of such characters that are
displayed by white glyph.  In addition to many NBSPs, that
char-table should also contain the following CJK white-space
characters:
 (make-char 'japanese-jisx0208-1978 33 33)
 (make-char 'chinese-gb2312 33 33)
 (make-char 'japanese-jisx0208 33 33)
 (make-char 'korean-ksc5601 33 33)
 (make-char 'chinese-cns11643-1 33 33)
 (make-char 'japanese-jisx0213-1 33 33)
 (make-char 'chinese-big5-1 33 33)
