<p>There might also be variable-width fonts similar to "Wingdings" that might assign custom icon to characters and could have the same width for $. and $w by accident. :P But Wingdings itself is not affected, I have checked.</p>

<p>By the way, maybe you already saw this, but this is how some other environments test this: <a href="https://stackoverflow.com/a/49299276/13994294" class="OWAAutoLink" id="LPlnk796646" previewremoved="true">https://stackoverflow.com/a/49299276/13994294</a></p>
<p><br>
</p>
<p>And for TrueType fonts, there appears to be optional metadata about monospacing: <a href="https://stackoverflow.com/a/43178653/13994294" class="OWAAutoLink" id="LPlnk421793" previewremoved="true">https://stackoverflow.com/a/43178653/13994294</a></p>
<p>But we don't seem to have easy access to this post table and it's probably not overly important. :D</p>
