Kerning<br>
Spacing<br>
<br>
As does XeTeX, and those features "not enabled" in pdfTeX. Nothing has<br>
"Expansion/manual" enabled either. Anyway, none of that is important in<br>
practice.<br>
<br>
The crucial thing in that table is that "Expansion/automatic" is enabled<br>
(green star) for PDF output of current luatex, while it is<br>
"not available" for XeTeX. Which is what I stated before.<br>
<br>
It's just one entry in that big table (attached for the heck of it, from<br>
microtype.pdf for version 3.2a, 2025/02/11), but it's the only<br>
difference that matters in practice for normal documents (e.g.,<br>
everything I've ever typeset for TUGboat). In my experience.<br>
<br>
If you actually run some sample documents with \usepackage{microtype}<br>
under both xelatex and lualatex, you will see the difference. --best, karl.<br>
