They seem to work fine for me, but I
spotted some weird behavior using `\displaylimits`*in in-line math*. In my
opinion, the limits of integration are placed way too much on the
right. The expected behavior is to have the same placement as with
`\nolimits` in in-line math, and as with `\limits` in display math. The
problem doesn't occur with XeLaTeX and it seems to be independent of a
font.
looks like an engine bug to me but it happens only if unicode-math is
used. But I don't think it is a problem of the package rather than a
problem of using OTF fonts.
A slightly simplified/altered example:
\documentclass{article}
\usepackage{unicode-math}
\showoutput
\begin{document}
$\int\nolimits_a^b \showlists$
$\int\displaylimits_a^b \showlists$
\end{document}
This shows, that the resulting math lists from TeX's point of view are
identical:
\mathop
.\fam0 ∫
^\fam0 𝑏
_\fam0 𝑎
in both lines. But the generated symbolic page output shows
.\TU/latinmodern-math.otf(1)/m/n/10 ∫
\kern-3.32 (font)
\vbox(15.46805+0.07)x7.39395, shifted 5.05505, direction TLT
for the formula with \nolimits but no \kern-3.32 (font)
for the second formula
I may be wrong (and it is late) but I think this negative value of
italic correction of ∫ which seems to get added when \nolimits are
explicitly used but not if the default is no limits or if \displaylimits
is used but we aren't in a display:
\documentclass{article}
\usepackage{unicode-math}
\showoutput
\begin{document}
$\mathop{f}\nolimits_a^b$
$\mathop{f}\displaylimits_a^b$
$\mathop{f}\nolimits\displaylimits_a^b$ % this overwrite the nolimits
\end{document}
here "b" hits the "f" in the first line
