<p>I just got the <code>line_height</code> workaround to work with excellent results. The <code>line_height</code> setting can be found in "Tools" > "Configuration Files" > "filetypes.common". To change this setting from its default <code>line_height=0;0;</code> there are two things to note:</p>
<ul>
<li><code>#~</code> lines are commented and have no effect.</li>
<li>The file format is an <a href="https://en.wikipedia.org/wiki/INI_file" rel="nofollow">INI file</a> so uncommenting the <code>line_height</code> line is insufficient because the <code>[styling]</code> section is also required; either uncomment this line or add a new <code>[styling]</code> section at the end.</li>
</ul>
<p>The only uncommented lines in my filetypes.common are now:</p>
<pre><code>[styling]
line_height=0;2;
</code></pre>
<p>With this setting and DejaVu Sans Mono Book size 12, underscores are visible. Using <code>line_height=0;1;</code> also works, but <code>line_height=0;2;</code> gives me, for the first time ever, exact agreement (as far as I can tell) with the line height in xfce4-terminal.</p>
