处理其中一种情况。对于其他情况,我提供\twofer{<accent>}{<two-lowercase-letter-string>
\documentclass{article}
\usepackage{graphicx}
\makeatletter
\newcommand\twofer[2]{\@firstoftwo#2\makebox[0pt]{\scalebox{1.8}[.95]{#1{}}}\@secondoftwo#2}
\makeatother

答案2
你可能会这样做:
\documentclass{article}
\usepackage{textcomp,graphicx}
\newcommand{\bbar}[1]{%
\leavevmode\vbox{%
\offinterlineskip
\halign{%
\hfil##\hfil\cr
\={}\kern-.4em\={}\cr
\noalign{\kern-1ex}
#1\cr
}%
}%
}
\newcommand{\revt}[1]{%
\leavevmode
\vphantom{\t{#1}}%
\smash{\vbox{%
\offinterlineskip
\halign{%
\hfil##\hfil\cr
\scalebox{1}[-1]{\capitalnewtie{}}\cr
\noalign{\kern.1ex}
#1\cr
}%
}}%
}
\begin{document}
\t{ar} \bbar{ar} \revt{ar}
\end{document}
