Just a quick note to myself, this issue is happened to me previously and I somehow forget how I fixed it. Yesterday I accidently enabled the Whitespace characters in ColdFusion Builder which in turn displays the new line (\n) and carriage return (\r) characters as well in the Editor.
This is how my editor looks even after the "Show whitespace characters" is unchecked under the Preferences > Editors > Text Editor Section of my ColdFusion Builder.
After a bit of goggling I get the solution from Raymond Camden blog for hiding the white space characters. So to Show or Hide the whitespace / New Line / Carriage Return Characters in ColdFusion Builder or Eclipse all we need to use is CTRL + . (CTRL + DOT) key combinations.
