PerlTeX is NOT a TeX engine (like XeTeX) but simply a wrapper that 
enables communication between TeX (or pdfTeX or XeTeX) and Perl and 
hence allows you to write macros in the Perl language instead of 
(La)TeX. I have not used it much, but since Perl is excellent at 
manipulating Unicode strings, that is certainly worth a look. AFAIK 
there is no reason why it should not work with XeTeX.
