LLMs are at a great disadvantage here because they operate on tokens, not letters.

I remember reading somewhere that LLMs are actually fantastic at reading heavily mistyped sentences! Mistyped to a level where humans actually struggle.

It's actually not. You can scramble every letter within words and it can mostly unscramble it. Keep the first letter and it recovers almost 100%.
