This is a nice addition to the manual, but it's not a docstring. A docstring is an attached to the module Unicode in the source code itself. (See the Writing Documentation section of the Julia manual.)

In particular, you would edit stdlib/Unicode/src/Unicode.jl to change the line module Unicode to something like:

"""
The `Unicode` module provides essential functionality for managing `Unicode` characters and strings.
It includes validation, category determination, normalization, case transformation, and grapheme segmentation,
enabling effective `Unicode` data handling.
"""
module Unicode

With this PR, there is a duplication of information on the docs page: The exact same sentence is first shown as a text, and then as the docstring of the Unicode module. Maybe there is a way to reduce that to one?

I think I can change the Docs one or should I remove it?

I don't think there is an easy way to write the sentence only once, so you should just leave it as-is.
