The difference between xetex and xelatex is the font:<br class="">

<div>I’m sorry but I don’t understand this as an answer.</div>
<div>I would expect the test of \lastkern to always give n </div>
<div>no matter what the driver, font, with LaTeX or not.</div>
<div><br class="">
</div>
<div>The result from \lastkern (according to the TeXBook)</div>
<div>is that it is only non-zero when the last item on the current list is a kern.</div>
<div>(It is *not* a place-holder for the last kern that has been used.)</div>
<div><br class="">
</div>
<div><br class="">
</div>
<div>Thus the appearance of the letter A should have reset \lastkern to 0,</div>
<div>*except* if there is a kern provided by A itself (font dependent, perhaps yes);</div>
<div>but in that case it is unlikely to have the value of 2019sp .</div>
<div><br class="">
</div>
<div>Of course, maybe this value has been chosen, *because* that font does end with such a kern. </div>
<div>This would be the only valid reason that you could ever get a y from this code.</div>
<div><br class="">
</div>
<div><br class="">
</div>
<div>Put another way, the result of the test should not depend upon the initial use of \kern2019sp at all.</div>
<div>However, if it is commented-out, then XeTeX does give n , so the y is *not* coming from the letter A .</div>
<div><br class="">
</div>
<div>To me this *does* indicate a bug; </div>
<div>or at least a difference in how XeTeX behaves, compared with the original TeX.</div>
