Common mistakes

The input is not actually ROT47 text

Fix: Check whether the source used ROT47 and not ROT13 or another format.

The user expects Unicode-heavy text to decode cleanly

Fix: ROT47 is mainly for printable ASCII text.

The user expects only letters to change

Fix: ROT47 affects many printable ASCII symbols too.

The user wants stronger decryption behavior

Fix: This tool only reverses ROT47 character rotation.

The result still looks unreadable

Fix: Confirm the input format and make sure the source really used ROT47.
