fix issue #48

One question

Unicode Characters: The test suite does not include a test to verify the Levenshtein Distance calculation for strings containing Unicode characters (e.g., "café" to "caffè").

so for you the distance here should be 2 or 3 ? and why?

[pankaj-bind]

Hey, the Levenshtein Distance for "café" to "caffè" is 2. You just swap "é" for "f" and add "è" at the end. That’s the shortest way to do it, and Pharo handles Unicode characters like single letters, so it’s all good!

Great
