public static bool IsMatch(string message)
{
var strMap = new Regex(PATTERN);
return strMap.IsMatch(message);

i make next tests :


string english_only = "dsfsdfsdf";

string Arabic_only = "دين الق";
string english_arabic_mix = "mixed englih with ك الدين القيم فل";



if test english_only =>i get true //correct

if I test english_arabic_mix ii get true
