$ emacs -q x.html # emacs-version "26.3"
The humble APOSTROPHE becomes a color change point, due to having a
FULLWIDTH LEFT PARENTHESIS before it.

    <p>（當然… Sure, you could say
      what does this matter to me? It's the <strong>farthest</strong>

    <p>計算您對蹠點極為容易： 只不過是經度轉一八○度， 緯度的南北互換。 Computing your antipode is so
      simple. Just rotate your longitude 180 degrees and flip your
      latitude's north vs. south.</p>
