 Wouldn't that end up mangling all non-ASCII characters in filenames (and a
 number of ASCII characters too), to the point of unrecognizability?

 For example, suppose I have a file named `alpha-beta-gamma-αβγ.png`.

 Currently, if I upload this to WordPress, the filename is stored
 unchanged.  The URL would be something like `https://example.test/wp-
 content/uploads/2025/06/alpha-beta-gamma-αβγ.png`.

 If I understand your proposal correctly, the filename would become `alpha-
 beta-gamma-%CE%B1%CE%B2%CE%B3.png`?  And the URL would be
 `https://example.test/wp-content/uploads/2025/06/alpha-beta-
 gamma-%25CE%25B1%25CE%25B2%25CE%25B3.png`?

 Another example: consider a file named `foo bar baz.png` (with spaces).

 Currently, if I upload this to WordPress, the filename becomes `foo-bar-
 baz.png`.  The URL becomes `https://example.test/wp-
 content/uploads/2025/06/foo-bar-baz.png`.

 Under your proposal, the filename would be `foo%20bar%20baz.png`?  And the
 URL would be `https://example.test/wp-
 content/uploads/2025/06/foo%2520bar%2520baz.png`?
