答案1
看起来像U+2ACD所以
\documentclass{article}
\usepackage{unicode-math}
\setmainfont{STIX Two Text}
\setmathfont{STIX Two Math}
\begin{document}
$ x ⫍ y$
\end{document}
答案2
在 egreg 回答这个问题之前:-)
...图片模式!(独立于引擎。)
\documentclass{article}
\usepackage{pict2e}
\usepackage{amsmath}% for scalable line thickness
\makeatletter
\newcommand*{\vargtr}{\mathrel{\mathpalette\var@gtr@less{(1,0)(0,0)(0,1)(2,1)}}}
\newcommand*{\varless}{\mathrel{\mathpalette\var@gtr@less{(0,0)(2,0)(2,1)(1,1)}}}
\newcommand*{\var@gtr@less}[2]{%
\setbox\z@=\hbox{\m@th$#1x$}%
\unitlength=\ht\z@
\begin{picture}(2,1)
\linethickness{%
\fontdimen8
\ifx#1\displaystyle\textfont\else
\ifx#1\textstyle\textfont\else
\ifx#1\scriptstyle\scriptfont\else
\scriptscriptfont\fi\fi\fi 3\relax}%
\roundcap\roundjoin
\polyline#2%
\end{picture}%
}
\makeatother
\begin{document}
$x \vargtr y \varless z$
$\scriptstyle x \vargtr y \varless z$
$\scriptscriptstyle x \vargtr y \varless z$
\end{document}
如果您希望符号具有与完全相同的宽度>
,<
则替换
\setbox\z@=\hbox{\m@th$#1x$}%
\unitlength=\ht\z@
经过
\setbox\z@=\hbox{\m@th$#1>$}%
\unitlength=.5\wd\z@
