This is similar to other encoding issues we have fixed lately where
we need to make sure Hugo (or Golang's HTML template library) does
not escape our non-ASCII content.
For example, this is how our datetimes end up currently:
<p class="blog-post-meta"><time datetime="2020-01-16T09:23:20+02:00">Thu Jan 16, 2020</time> by Alan Orth
After printing them with `printf` and filtering them with the Hugo
built-in function `safeHTMLAttr` they look like this:
<p class="blog-post-meta"><time datetime="2020-01-16T09:23:20+02:00">Thu Jan 16, 2020</time> by Alan Orth

This became a problem when I added right-to-left language support.
When you mix RTL languages like Arabic with English (even for just
dates and small strings) everything becomes jumbled. For now I have
only added translations for English (default), Arabic, and Bulgarian.
