Sure.
EcmaScript compliancy for regular expressions controls various aspects
of how the regex engine behaves for them. These aspects include whether
unicode character classes support is enabled or not (EcmaScript does not
support unicode), how certain types of character escapes are treated and
how backreferences are interpreted [1].
You can set EcmaScript compliancy as all of the other regular expression
options, using a combination of the values of the RegexOptions
enumeration [2], applied to the Regex constructor.
