 I've investigated the possible influence of [https://wiki.php.net/rfc
 /strtolower-ascii| this PHP 8.2 change] on WordPress.
 Please see the examples below:
 https://3v4l.org/9OGQo/rfc#v8.1.9 <- PHP 8.1 (and below)
 https://3v4l.org/9OGQo/rfc#vgit.master <- PHP 8.2
 The test fails on PHP 8.2 too. But, at least, `strtoupper()` doesn't
 "corrupt" the string.
 This is some good news. As can be seen from the test, PHP 8.2 better
 processes multibyte characters passed to "regular" (non-mbstring) string
 functions.
 I haven't found any differences in processing extended ASCII characters
 (128-255) in PHP 8.2 compared to PHP 8.1.
