Although there may be other ways this happens, whenever I add a blank line between paragraphs by using the ENTER key to create a blank line, I get this set of spurious characters: ​

The blank line is formed using the following: <p>​</p>

If I subsequently delete the blank line, the P tags are removed, but the spurious characters often remain. This reaction is not, however, consistent, or so it seems.

In the css style sheet, the P tag uses the following:
font-family: Verdana, Arial, Helvetica, sans-serif;
font-size: 12px;
font-style: normal;
line-height: 16px;
font-weight: normal;
font-variant: normal;
text-transform: none;
color: #000000;
text-indent: 20px;
margin-bottom: 0px;
margin-top: 0px;

There may be other ways to cause these characters appear, but using the ENTER key to create a blank line seems to cause this hiccup reliably. The problem also surfaced in the previous version of the HTML editor and online page editor add-on combination.

Hello Michael,

I see you are using: charset=iso-8859-1
Please change your page encoding to utf-8.

That solved it. Thanks!
