Well, X-Symbol was focused on providing math mainly for LaTeX, and the
STIX project's mission <URL:http://www.stixfonts.org/project.html>
states "All characters/glyphs have been incorporated into Unicode
representation or comparable representation and browsers include program
logic to fully utilize the STIX font set in the electronic
representation of scholarly scientific documents" can more succinctly be
expressed as "let Barbara Beeton dump all of AMSTeX into Unicode".

So indeed I should be surprised if the current state of Unicode did not
actually cover most of X-Symbol satisfactorily by now.
