Hi Roberto,

That surprises me as well. I guess .NET is able to handle the unescaped right
parenthesis in the passing case. NUnit's RegexConstraint does no processing
of the string but just passes it on to Regex.IsMatch.

Title:
  Exception in -Is.StringMatching(string)- method

Status in NUnit Test Framework:
  New

Bug description:
  This is my code:

        [Test]
        public void Test_NUnitBug()
        {
            const string ExpectedString = "NUnit is :) happy!";
            Encoding encoding = Encoding.Unicode;
            byte[] bytes = encoding.GetBytes(ExpectedString);
            string actualString = encoding.GetString(bytes);

            Console.WriteLine(actualString);
            Console.WriteLine(ExpectedString);
            Console.WriteLine(actualString.Length);
            Console.WriteLine(ExpectedString.Length);
            Assert.That(actualString, Is.StringMatching(ExpectedString));
        }

This is the exception:

NUnit is :) happy!
NUnit is :) happy!
