The last resort is define-category where we can manage exceptions.
But I think that even without distinguishing ?¿, we can improve the
situation for CJK users a lot.

We can probably split character categories into "left", "right", and
"neutral" with "(" being "left" example, ")" being "right" example, and
" " being "neutral" example.
We start from using the information we can extract from Unicode data and
modify it as necessary.

Then, emphasis will be defined as PRE MARKER ... MARKER POST with
PRE = left+neutral category
POST = right+neutral category
