But there's a double-joke in there. You see, not every character in the United States Constitution can be represented in ASCII!
If you take a close look, you'll see that some words appear to be "misspelled": At the end of the second line, it says "Bleſsings of Liberty", and Article 1 Section 1 declares that "All legislative Powers herein granted shall be vested in a Congreſs of the United States."
That f-like character is actually a long S, a character which has fallen into disuse in modern English. It also doesn't exist in ASCII.
My friend The Knitty Professor told me a story of a class she taught many years ago. A student emailed a question:
Today is Constitution Day, a United States holiday celebrating the United States Constitution. Since 2005, all educational institutions which receive federal funds must teach about the United States Constitution on this day, even hairdresser schools.
