least \nm was preceded by at least nm, then NM is a back reference. If there are at least N fetches before \nm, then N is a back reference followed by the literal m. If none of the preceding conditions are met, if both N and M are octal digits (0-7), then \nm will match the octal escape value nm.\NML if n is an octal number (0-3) and both M and L are octal digits (0-7), the octal escape value NML is matched.The \un matches n, where N is a Unicode character represented by four hexadecimal digits
