* Custom resources can be listed with a set of grouped resources (category) by specifying the categories in the [CustomResourceDefinition spec](https://kubernetes.io/docs/tasks/access-kubernetes-api/extend-api-custom-resource-definitions/#categories). Example: They can be used with `kubectl get important`, where `important` is a category. ([#59561](https://github.com/kubernetes/kubernetes/pull/59561), [@nikhita](https://github.com/nikhita))

<p>
In <a href="https://www.unicode.org/versions/Unicode8.0.0/">The Unicode Standard 8.0</a>,
Section 4.5 "General Category" defines a set of character categories.
Go treats all characters in any of the Letter categories Lu, Ll, Lt, Lm, or Lo
as Unicode letters, and those in the Number category Nd as Unicode digits.
