Quote \, _, ' and % characters

(for example, '\n' to represent newline), you must double
any '\' that you use in your LIKE strings. For example, to
search for '\n', specify it as '\\n'. To search for '\', specify
it as '\\\\' (the backslashes are stripped once by the parser
and another time when the pattern match is done, leaving a
single backslash to be matched).
Example: "t\1" => "t\\\\1"
