You do, of course, restrict the user's input to a single word before showing it to the AI (to avoid jailbreaks)?

But to answer your question - yes the string must contain only valid english letters and must be between 2-25 characters in length. If you can jailbreak the system with those constraints I salute you!

Others have tried and failed to jailbreak it. Give it a shot if you're keen and post results here.
