Loading collection data...
Collections are a way for you to organize kata so that you can create your own training routines. Every collection you create is public and automatically sharable with other warriors. After you have added a few kata to a collection you and others can train on the kata contained within the collection.
Get started now by creating a new collection.

Yes, I think so. Either change the description or the description and the tests. The choice is up to you, it's your kata after all :)
Well I might change the kata description so that the solution also accepts all the UTF-8 characters, I think this would be better ?
Instructions not clear... I'm not sure whether to return an object or a stringified object. :-/
EDIT: OK, the function needs to return an object. :p
