Many thanks for your reply, Hans.

I’m afraid that "stretch" doesn’t make any difference with TeX Gyre
Heros (https://pdf.ousia.tk/stretch-mkxl-hz.pdf) and it only corrected
one problematic case with Source Serif Pro
(https://pdf.ousia.tk/stretch-ssp-mkxl-hz.pdf).

Sorry if I hadn’t expressed myself accurately before. The issue here
isn’t having exactly the same output in both MkIV and MkXL. The real
problem is that characters are misplaced in MkXL with hz enabled. I
think this might be a bug.

Many thanks for your help,

Pablo
