When viewing the HTML output from my website using the code inspector within Google Chrome, I get the spurious character
​ being injected in my code (snipped screen capture below).
It looks like ​ is a zero width space, but what is causing it?
To check it is not Google Chrome, I tried it in Firefox, and I get red dots, which if hovered, they show a caption of
\u200b(snipped screen capture below).
I don't understand what is going on here because when, instead of visual mode, I view the block in HTML mode within WordPress (click the three dots on top of the block and click 'Edit as HTML') I have the following...
<p>Because it suggests something is being presented as science inaccurately or even deceptively, the term pseudoscience is often considered defamatory (<a href="https://plato.stanford.edu/entries/pseudo-science" target="_blank" rel="noreferrer noopener nofollow" aria-label=" (opens in a new tab)">Hansson, 2008</a>). Accordingly, those termed as practising or advocating pseudoscience often dispute the characterization (<a href="https://en.wikipedia.org/wiki/Pseudoscience" target="_blank" rel="noreferrer noopener nofollow" aria-label=" (opens in a new tab)">“Pseudoscience,” n.d</a>.).</p>
No extra spaces or weird characters
What I have tried so far
- Jetpack's spell checking facility adds code bloat which I had to manually remove so I disabled that and used Microsoft Word for spelling and grammar checking. This may have caused the issue, as suggested in comments, so I tried the suggestion to "put it in Notepad, then copy it again to the clipboard, and paste it on your WordPress", but the spurious injections are still there.
- The same goes when adding a new article with the same information, but the notepad content pasted into the WordPress article content.
- I have checked that it is not a plugin injecting the code by deactivating them one by one.
What is going on? How do I stop these spurious character codes being injected?
In case you need to see the full coding on the live site, go to http://www.whatstheproblem.co.uk/psychology/pseudoscience-in-psychology/ and it is in the last paragraph of the section "What is Pseudoscience?"
