If you want a literal \ in your strings, you should write it as \\.

The \ character starts an escape sequence and neither # nor : are valid as the second character. It's meant to allow for things like newline \n or tab \t.

Of course, if you don't wish to have \ in your resultant string, just remove it altogether.
