Recently I received the following message. Try to read it.

That’s fun. I decided not to forward it but to start playing with the rep1@(emen7 0f 1e77er$.

I took the opening sentences of 3 of my favorite books and got the following results.

The original texts

For nutcases and nincompoops.

It is a truth universally acknowledged, that a single man in possession of a good fortune, must be in want of a wife.

Jane Austen – Pride and Prejudice

Mr. and Mrs. Dursley, of number four, Privet Drive, were proud to say that they were perfectly normal, thank you very much. They were the last people you’d expect to be involved in anything strange or mysterious, because they just didn’t hold with such nonsense.

J.K. Rowling – Harry Potter and the Philosopher’s Stone

In a hole in the ground there lived a hobbit. Not a nasty, dirty, wet hole, filled with the ends of worms and an oozy smell, nor yet a dry, bare, sandy hole with nothing in it to sit down on or to eat: it was a hobbit-hole, and that means comfort.

What’s next?

I then decided to make a web page where you can enter your own text to replace letters with numbers or other stuff. This page (Letter Replacer) gives you some flexibility in the letters you want to replace and some other options to play with. Have fun.
