用点划线划线

如何用点划线给单词加下划线？

实际上，单词下方应该有一条点划线，而这条线下方应该是一条虚线。

注意：我知道，不应该加下划线。

例子：

longword
._._._._
_ _ _ _

主要基于https://tex.stackexchange.com/a/27260/36296

\documentclass{article}

\usepackage{tikz}

\newcommand{\mydash}[1]{%
    \tikz[baseline=(todotted.base)]{
        \node[inner sep=1pt,outer sep=0pt] (todotted) {#1};
        \draw[dash dot] (todotted.south west) -- (todotted.south east);
        \draw[dashed] ([yshift=-2pt]todotted.south west) -- ([yshift=-2pt]todotted.south east);
    }%
}%

\begin{document}

\mydash{double line}

尽管上述解决方案对要加下划线的单词的位置很敏感（例如，如果j单词中有字母），但以下解决方案会将线放在相同的位置，而不管字符是什么。

 \documentclass{article}

\usepackage{tikz}
\usepackage{lipsum}

\newcommand{\mydash}[1]{%
    \tikz[baseline=(todotted.base)]{
        \node[inner sep=1pt,outer sep=0pt] (todotted) {\strut #1};
        \draw[dash dot] ([yshift=3pt]todotted.south west) -- ([yshift=3pt]todotted.south east);
        \draw[dashed] ([yshift=2pt]todotted.south west) -- ([yshift=2pt]todotted.south east);
    }%
}%

\begin{document}

\mydash{doguble line}
\lipsum[2]

\mydash{double line}
\lipsum[2]

\end{document}

更新了虚线和虚线点。并且不再影响下行的间距。

\newcommand{\underDotDash}[1]{%
    \parbox[b][0pt][l]{0pt}{%
      \raisebox{-.3ex}{%
        \makebox[\widthof{#1}]{%
          \xleaders\hbox{\rule{.8ex}{0.5pt}\,\rule{.5pt}{0.5pt}\,}\hfill}%

      }
    }%
  #1%
