RegularExpression = 11
Regular expression - The first cstring is the regex pattern, the second is the regex options string. Options are identified by characters, which must be stored in alphabetical order. Valid options are ‘i’ for case insensitive matching, ‘m’ for multiline matching, ‘x’ for verbose mode, ‘l’ to make \w, \W, etc. locale dependent, ‘s’ for dotall mode (‘.’ matches everything), and ‘u’ to make \w, \W, etc. match unicode.
