Summary | 0001002: Shifting underbrace issue due to nested \Umathaccent | ||||
Description | Reporting from an old (but still relevant) bug on tex.sx: <https://tex.stackexchange.com/questions/323797/shifting-underbrace-with-lualatex-and-unicode-math> The issue in plain LuaTeX is reproduced below. As noted on the page above, it can be fixed with something like \underbrace{{}\hat{z}+w} As far as I can see this isn't intended behaviour. | ||||
Steps To Reproduce | \input ifluatex.sty \ifluatex \input luaotfload.sty \fi \font\mf="[latinmodern-math.otf]" \textfont1=\mf \scriptfont1=\mf \scriptscriptfont1=\mf \protected\def\underbrace#1{% \mathop{\Umathaccent bottom 7 1 "023DF\relax {0000001}}\limits } \protected\def\hat{\Umathaccent fixed 7 1 "00302\relax} $\underbrace{z+w}_y$\qquad$\underbrace{\hat{z}+w}_{y}$ \bye | ||||
