If nobody believes you, I must be nobody. I have never been able to get
this to work. I was about to try with two percent signs when I read
this. Being curious, I opened a xelatex document with the following
second line (the first - allegedly - sets the encoding):
%!TEX TS-program = XeLaTeX
-> result: pdflatex runs and complains, predictably that it can't
manage, that xelatex is needed etc. etc.
I change the second line:
%%!TEX TS-program = XeLaTeX
-> result: xelatex runs, compiles document
I change the second line:
%!TEX TS-program = XeLaTeX
-> result: xelatex runs, compiles document
I change the second line:
%!TEX TS-program = PDFLaTeX
-> result: pdflatex fails
I change the second line:
%!TEX TS-program = XeLaTeX
-> result: xelatex compiles document

I don't believe you mistyped anything. In any case, I _know_ I did not.
The changes shown are the _only_ changes I made to the file.

Yours,
