Code to change text to Leet

This is a little funny method that changes text to Leet[^] text. It is a C# version of a website[^] translator.

1 th1nk 1t 1s fun t0 us3 4nd m4k3s y0ur br41n w0rk t0 f1nd 0ut wh4t 1t s4ys.
1s 1t us3ful, m4yb3?
1s 1t funny, y3s :-)

To use it, just call the static method Translate that takes two parameters: a string that has to be translated to Leet and an integer that tells the degree of translating.

C#
// Original text
string myText = "Leet Translator";

// Translated text
string leetText = Leet.Translate(myText, 30);

// Output is: L33t Tr4nsl4t0r
Console.WriteLine(leetText);

// Do it again, and change degree to 100.
string leetText = Leet.Translate(myText, 100);

// Output is: £337 7®4|\|$£470®
Console.WriteLine(leetText);

// Leet class has an extension method to string class that allows us to
// Output is: L33t Tr4nsl4t0r
Console.WriteLine(myText.ToLeet());

Here is the Leet class:

C#
public static class Leet
{
    /// <summary>
    /// Translate text to Leet - Extension methods for string class
    /// </summary>
    /// <param name="text">Original text</param>
    /// <param name="degree">Degree of translation (0 - 100%)</param>
    /// <returns>Leet translated text</returns>
    public static string ToLeet(this string text, int degree = 30)
    {
      return Translate(text, degree);
    }
    /// <summary>
    /// Translate text to Leet
    /// </summary>
    /// <param name="text">Original text</param>
    /// <param name="degree">Degree of translation (0 - 100%)</param>
    /// <returns>Leet translated text</returns>
    public static string Translate(string text, int degree = 30)
    {
      // Adjust degree between 0 - 100
      degree = degree >= 100 ? 100 : degree <= 0 ? 0 : degree;
      // No Leet Translator
      if (degree == 0)
        return text;
      // StringBuilder to store result.
      StringBuilder sb = new StringBuilder(text.Length);
      foreach (char c in text)

Decoding Leet text will not give the original text back.
Char like 'g' and 'G' is both encoded to '9'. To decode it, the text will either be UPPER or lower case. But yes it is possible Smile | :)
