comment Too much space after integral sign with unicode-math and lualatex
@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?

comment Why no metrics for left subscripts and superscripts?
@Steve As far as I remember, original TeX "cheats" a bit to make the the metrics files more compact (see this for details, but I don't want to read it all again just for this comment). Each glyph has (roughly speaking) a box size, an accent position and an italic correction. The latter is used for positioning of superscripts. That is why f^2 looks great, but \Gamma_2 requires some negative space. The metrics tell next to nothing about the shape on the left of the glyph.

@barbarabeeton Sorry, here you go: undead link.

This and that article seem to indicate that, at least for OpenType math fonts, there are specific metrics for right subscripts and superscripts.

@Mico, see the example above to see what I mean.

comment Why no metrics for left subscripts and superscripts?
Well, the parameters for suffixed subscripts and superscripts were never intended for left subscripts and superscripts and often yield unsatisfactory spacing, both vertical and horizontal. I have also seen approaches based on putting a \vphantom on the left; but that is usually not very pretty either. Left superscripts are often too high, for instance.

comment Why no metrics for left subscripts and superscripts?
Yes I know it. To quote the manual, "A fairly robust (if somewhat crude) attempt is made to ensure the correct spacing and skew of the preposed indices with respect to the tensor object itself." To me, that does not sound like an actual solution, but a rather ad-hoc approach, which may or may not yield the expected results.

comment Redefining the emdash so as to allow hyphenation
And can this somehow be done in LuaLaTeX, too?

Thank you for your quick fix. :-)

comment Writing a token list conditional with expl3
It appears not to work if the argument does not start with a number. So \isinteger{n} fails.

comment Adequate hyphenation of words already containing a hyphen
Any updates on this? Can LuaTeX be made to do this automatically yet?

I would like to know that as well.

comment Grid on aligned equations in ConTeXt
You're right, finally got in touch with Hagen himself. It appears there will be a fix in an upcoming beta.
