I attempted to reproduce this. It took 6 attempts, but it gave me this:
Yes, I can help you decode this poem! It looks like your friend used a substitution cipher to encrypt the original text. A substitution cipher is a type of encryption where each letter in the plaintext is replaced by a different letter or symbol in the ciphertext. To decode it, we need to figure out which letter each symbol corresponds to.
One common type of substitution cipher is the Caesar cipher, where each letter is shifted by a certain number of positions in the alphabet. However, it doesn't seem like that's what your friend used, as some symbols appear multiple times and the distribution of symbols doesn't match the distribution of letters in English.
Another type of substitution cipher is the monoalphabetic cipher, where each letter is replaced by a fixed symbol. This seems more likely given the pattern of repeated symbols in the ciphertext. To decode it, we can try to match up the symbols with the most common letters in English and work from there.
Here's the original text, decoded from the ciphertext using a monoalphabetic substitution cipher:
The woods are lovely, dark and deep,
But I have promises to keep,
And miles to go before I sleep,
And miles to go before I sleep.
Stopping by Woods on a Snowy Evening
By Robert Frost
I hope that helps!
I must now agree that it was only just a lucky guess. I'm embarrassed that I didn't verify this more before posting./sigh.
