Note Because MySQL uses C escape syntax in strings (for example, ³\n² to represent a newline character), you must double any ³\² that you use in LIKE strings. For example, to search for ³\n², specify it as ³\\n². To search for ³\², specify it as ³\\\\²; this is because the backslashes are stripped once by the parser and again when the pattern match is made, leaving a single backslash to be matched against. (Exception: At the end of the pattern string, backslash can be specified as ³\\². At the end of the string, backslash stands for itself because there is nothing following to escape.)
