Don't Display Footnote Number on Excerpt

The number ‘1’ after the end of sentence is a footnote, which probably shouldn’t be displayed in the excerpt:

Thanks! I'll add this to the Next Release milestone.

Hmm, taking another look at this now. This is going to be a bit tricky.

Currently, I search for and strip out any <div> with a class="footnotes", but the problem here is the <sup> tag that adds the 1, which links to the footnotes.

I'm wondering if I should even be worrying about this in the core theme. This seems like something a site owner should specify on their own in a child theme, using CSS, since each site owner may implement footnotes differently.

For example, there are WordPress plugins for adding footnotes to your posts and I have no way of detecting how those are implemented and therefore would not be able to automatically remove them.

OK, problem solved. For Quote and Aside post formats, the theme now strips out any anchor tags and any footnotes (<sup></sup>) from the content before linking the content to the permalink (on blog, archive, and search pages).

It's just not possible to show an anchor tag inside the Quote or Aside content on the Blog, Archive, or Search pages, because on those pages the Quote and Aside content is linked to the permalink for the Quote or Aside, and nesting anchors inside anchors doesn't work (e.g., <a href="permalink"><div class="entry-content">Some content with <a href="#">a link</a></div></a>).
