[RFC]: improve README examples of `constants/unicode` namespace

[Planeshifter]

Description

This RFC proposes to improve the README examples of the constants/unicode namespace package. Currently, namespace package READMEs only include minimal examples which are not particularly informative and do not showcase namespace functionality.

Historically, namespace examples were not given much effort due to the rapidly changing nature of the project; however, now that development and organization has settled, it would be good to revisit these packages and add proper examples to better communicate to users how to use namespace contents.

For those wanting to contribute to this issue, you can use the following steps:

• Browse through the contents of the constants/unicode namespace and identify interesting functions and packages to showcase.
• Update the example code block in the "Examples" section of the README for the constants/unicode namespace and open a PR.
• When updating the README, examples should follow existing project conventions (e.g., ES5).
• Examples may require functionality from other packages to help make examples more interesting.
