What have you tried? If not String::Approx then that might be worth a look. You could specify there to be a maximum of 1 substitution with no insertions or deletions which I guess would fulfil your requirements.

The question is also sufficiently general that it says nothing about the use case. It could well be that there is a more appropriate method which relies on some domain knowledge. Without the context we cannot know about this.
