u can copy the code & symbol ( a permanent space that replaces the red dot " " ) by editing my page
I was wrong, and the red dot will not be replaced  , here is the real meaning.
The&.nbsp; stands for "Non-Breaking SPace". It is a character entity used to insert a space that the browser does not break into a new line. Unlike a normal space, which the browser collapses and can cause line breaks, a non-breaking space(& nbsp;) keeps the text together on the same line
