HTML entities often appear in CMS editors after copy-paste, imports or template edits. Sometimes they are correct. Sometimes they are double-encoded and show visible fragments like & instead of a normal ampersand.
Use HTML Decode Text to inspect encoded text and HTML Encode Text when you need to show characters safely inside HTML examples.
Do not decode everything blindly
If text is inside an HTML example, entities may be intentional. Decoding them can turn a visible example into real markup.
Watch double encoding
Double encoding often leaves text that looks half-readable but still contains fragments like <. Decode once, review, then decide whether another pass is needed.
Check before publishing
Preview the CMS page. The editor view and the frontend output may not treat entities the same way.
