I don't understand. I ran the "TestThatPasses()" method (below) and it passes. 
It is the exactly same regular expression. Am I doing something wrong?

        [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));
        }

 

        [Test]
        public void TestThatPasses()
        {
            const string ExpectedString = "NUnit is :) happy!";
            Console.WriteLine(ExpectedString);
            Console.WriteLine(ExpectedString.Length);
            Assert.That(ExpectedString, Is.StringMatching(ExpectedString));
        }

Asunto: [Bug 697919] Re: Exception in -Is.StringMatching(string)- method

Is.StringMatching() takes a string argument, which is to be used as a
regular expression. Hence, it must be a valid regular expression. You
should either use Is.EqualTo() or escape the ')' like this: @"NUnit is
:\) happy!"

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!
