Dear Hans (and others),
In the tex stackexchange chat today we were discussing the stix two fonts, and in particular the spacing between the integral sign and the lower bound. It is known that this was way to big before (see
https://tex.stackexchange.com/q/327710/52406), but it seems that it is still too big, at least if one uses the upright version. Judge yourself from the example file at the end of this email (result attached).
Can you do that for this one as well?
During the discussion Harald Hanche-Olsen came up with the following "quick fix" for LuaLaTeX:
\usepackage{luatexbase,luacode}
\begin{luacode}
local patch_stixmath = function (fontdata)
if fontdata.psname == "STIXTwoMath"
then
fontdata.characters[983352]["italic"]=3*fontdata.characters[983352]["italic"]
end
end
luatexbase.add_to_callback
(
"luaotfload.patch_font",
patch_stixmath,
"change_stixmath"
)
\end{luacode}
I don't know if this is the way to go, but I thought I should include it.
Best regards, Mikael
