Double underline, one of them dashed

Question

Anyone knows any word processor that can do a double underline; one normal line and the other a dashed line?

preferably a linux-native

something similar to this:

It's also fine if the dashed line is the top one.

Answer 1

LaTeX can do that. And much more.

Try it out with ShareLaTeX, it's free.

When you have a LaTeX setup working, try this code:

\documentclass{article}
\usepackage[utf8]{inputenc}
\usepackage{tikz}

\title{\specdash{Some Text}}
\author{\specdashtwo{Author}}
\date{\specdashthree{20 October 2016}}

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

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

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

\begin{document}

\maketitle

\end{document}
\documentclass{article}

Here's a screenshot of the output of the above code:
