A (horizontal) space after a special character
LaTeX does not recognise a space we produced by using a space bar after a special character.
To have a space after such a special character we have to put \; after it.
%Insert a copy right logo followed bythe text "All Rights reserved" \copyright All Rights Reserved
Output: <- No space after
%Put a space between a copyright logo and the text "All Rights reserved" \copyright \; All Rights Reserved
Output: <- There is a space after
