Let me clarify:

Org-mode should work fine with files containing text in any
encoding, including Asian languages and whatnot.  At least
this is what I aim for.

What you are referring to was a post where I said that I want the basic
syntax like todo keywords, tags, list bullets etc to be ASCII as much
as possible.

I would not mind to include a general class of open-quote and
close-quote characters into the character class in the emphasis
regular expression.  However, as far as I know, this is not
possible.  Syntax classes can do what Daniel wants, but only
partially.  However, syntax classes cannot be used in regular
expressions.  There are a few exceptions like [:digit:], but
quotes and parenthesis are not supported, and none of these
special [:classes:] are available in XEmacs.

I have read mastering regular expressions, and yes, in Perl, syntax
classes can be used in regular expression character classes.
Not so in Emacs - unless something has changed here.
