It should not be used for HTML from a third-party, or HTML with unclosed tags or comments.
Given a site-wide [`config.toml`][config] with the following `copyright` value:
{{< code-toggle file="config" >}}
copyright = "© 2015 Jane Doe. <a href=\"https://creativecommons.org/licenses/by/4.0/\">Some rights reserved</a>."
{{< /code-toggle >}}
`{{ .Site.Copyright | safeHTML }}` in a template would then output:
```
© 2015 Jane Doe. <a href="https://creativecommons.org/licenses/by/4.0/">Some rights reserved</a>.
```
However, without the `safeHTML` function, html/template assumes `.Site.Copyright` to be unsafe and therefore escapes all HTML tags and renders the whole string as plain text:
```
<p>© 2015 Jane Doe. &lt;a href=&#34;https://creativecommons.org/licenses by/4.0/&#34;&gt;Some rights reserved&lt;/a&gt;.</p>
```
