            int characterCount = 10000; // count of characters to generate

            StringBuilder builder = new StringBuilder();
            
            // iterate, get random int between 'asciiCharacterStart' and 'asciiCharacterEnd', then convert it to (char), append to StringBuilder
            for (int i = 0; i < characterCount; i++)
                builder.Append((char)(random.Next(asciiCharacterStart, asciiCharacterEnd + 1) % 255));

            // voila!
            String text = builder.ToString();
        }
    }
}

Lovely script mate! Borrowed it and played around with it a little bit to make some text glitcher.
