(I had a feeling this was a duplicate, but couldn't find an older question about it. Forgive me if I'm just bad at searching.)

Consider the minimal example

  \int f(x) \, \mathrm{d}x

When compiled with lualatex the space between the integral sign and f(x) is too large, larger than what I get if I compile with xelatex (or if I'm not using unicode-math).

  • With lualatex:

  • With xelatex:

  • Without unicode-math:

I'm using a recently updated TeXlive 2011, and the same thing happens with Asana-Math.otf or xits-math.otf as math font. Can this be corrected somehow?

Happens the same to me. – egreg Nov 30 '11 at 21:10

Update 28-10-2015: This has been fixed in version 0.85 of LuaTeX, see

Looks something wrong with italic correction of integrals in the absence of super or subscripts, adding an empty superscript \int^{} f(x) fixes the spacing. Odd enough, adding empty subscript \int_{} f(x) makes it even closer! I'd report this to luatex bug tracker.

After tracking down the bug tracker, it seems you've reported this already, about a year ago: – Torbjørn T. Dec 1 '11 at 0:05
Or, that issue doesn't say anything about unicode-math, so it is somewhat different. Should I make a new issue, or just add a comment to that one? – Torbjørn T. Dec 1 '11 at 7:53
I can confirm that this bug is still in TL2014. Is it going to be fixed anytime soon? – Gaussler May 29 at 11:00
@KhaledHosny, it also happens in TL2015. Sorry to say it, but it makes unicode-math pretty much useless for serious production work. Has no workaround been found yet? – Gaussler Aug 17 at 13:23
This, along with the incorrect positioning of sub-/superscripts for integral signs (, which is supposedly the same bug), really destroys any use unicode-math might have offered. Why is this issue being ignored? – Socob Sep 21 at 1:05
