LuaLaTeX + unicode-math results in wrong mkern and mskip

In a personal package I tested mkern and mskip for different values using pdfLaTeX and LuaLaTeX, I discovered that the spacing using mkern0mu and mskip0mu seems to leave a negative space of -1.1mu. This is shown in the mwe below. Removing unicode-math gives the correct space. However using XeLaTeX with and without unicode-math gives the correct space, same for pdfLaTeX and amsmath. Is this a bug?

  • comparison with showoutput of xelatex and lualatex shows that in former case there is always after the partial a kern0.63 which however in the latter engine disappears as soon as one uses mkern.

When mkern is used the default (italic) kern is removed. You can set mathitalicsmode=1 to change this behaviour:



documentclassarticle
usepackageamsmath
usepackageunicode-math
begindocument
showoutput
 $partial mkern 1.1mu t = partial t neq partial mkern 0mu t$

mathitalicsmode=1

 $partial mkern 1.1mu t = partial t neq partial mkern 0mu t$

enddocument

White Anglo-Saxon Protestant

Image
White Anglo-Saxon Protestants ( WASPs ) are a social group of wealthy and well-connected white Americans, of Protestant and predominantly British ancestry, who trace their ancestry to the American colonial period. Until at least the 1960s, this group has dominated American society and culture and dominated in the leadership of the Whig and Republican parties. They usually are very well placed in major financial, business, legal and academic institutions and had close to a monopoly of elite society due to intermarriage and nepotism. [1] During the latter half of the twentieth century, outsider ethnic and racial groups grew in influence and WASP dominance weakened. Americans are increasingly criticizing the WASP hegemony and disparaging WASPs as the epitome of "the Establishment". The Random House Unabridged Dictionary (1998) says the term is "Sometimes Disparaging and Offensive". [2] [3] The term WASP is often used as a pejorative to classify their historical dom...

One-line joke

A one-liner is a joke that is delivered in a single line. A good one-liner is said to be pithy - concise and meaningful. [1] Comedians and actors use this comedic method as part of their act, e.g. Jimmy Carr, Tommy Cooper, Rodney Dangerfield, Norm Macdonald, Ken Dodd, Stewart Francis, Zach Galifianakis, Mitch Hedberg, Anthony Jeselnik, Milton Jones, Shappi Khorsandi, Jay London, Mark Linn-Baker, Demetri Martin, Groucho Marx, Dan Mintz, Emo Philips, Tim Vine, Steven Wright and Henny Youngman and Arnold Schwarzenegger. [ citation needed ] Many fictional characters are also known to deliver one-liners, including James Bond, who usually includes pithy and laconic quips after disposing of a villain. [ citation needed ] Examples "A baby seal walks into a club." "A dyslexic man walks into a bra." (Anonymous) "There are three types of people, those who can count and those who can't." "Venison's dear, isn't it?" (Jimmy Carr) "An escala...
