`utf8mb4` is the complete UTF-8 implementation in MySQL, supporting the full range of Unicode characters by using up to 4 bytes per character. This includes characters outside the Basic Multilingual Plane, such as emoji and supplementary characters. `utf8mb4` ensures full compatibility with modern text content and diverse character sets.
As of WordPress 4.2, on both new and existing installations, WordPress would automatically upgrade database tables to `utf8mb4` on compatible servers (MySQL 5.5.3 or later). However, the default `DB_CHARSET` value during setup was still set to `utf8` for compatibility with older MySQL versions.
As of WordPress 6.5, the minimum required MySQL version is 5.5.5, so the default can be updated to `utf8mb4`.

This restores "That's all, stop editing!" line to its previous format, to avoid breaking external integrations looking for that format specifically.

Help prevent errors from users who are less familiar with php from adding code in side the comment block and thus having their code not work. Therefore, this comment is now a single line.

This avoids the performance overhead of the function call every time `dirname( __FILE__ )` was used instead of `__DIR__`.
This commit also includes:
* Removing unnecessary parentheses from `include`/`require` statements. These are language constructs, not function calls.
* Replacing `include` statements for several files with `require_once`, for consistency:
* `wp-admin/admin-header.php`
* `wp-admin/admin-footer.php`
* `wp-includes/version.php`

As of this commit, WordPress is no longer a simple blogging platform. It's now a comprehensive publishing solution.
This also replaces a couple of other "blog" references that were missed previously.

* Fixes some grammatical and wrapping issues in the file header, and breaks the contents list up into, well, a list.
* Adds a note and Codex link to the DocBlock for the `WP_DEBUG` constant definition on where to find more information about constants used for debugging.

* The WPLANG constant is no longer needed. Remove define('WPLANG', ''); from wp-config-sample.php. Populate WPLANG option based on the WPLANG constant. When get_option('WPLANG') is an empty string it will override WPLANG.
* Introduce translations_api() which is available to communicate with the translation API. Move translation install related functions to a new file.
* Replace mu_dropdown_languages() with wp_dropdown_languages(). wp_dropdown_languages() is now populated by the translation API.
* Remove wp_install_load_language() and allow load_default_textdomain() to switch a core translation.
