Comment (by afercia):

 @SergeyBiryukov, @poena, and I had a look at this ticket in a mob coding
 session. We do support @jrf proposal to require the `mbstring` extension
 as that appears to be the most future-proof way to address this issue.

 We think a polyfill wouldn't be ideal because of the important point
 raised by @jrf:

 > As most uses of these functions are likely to be incorrect usage
 (especially in plugins), these "bugs" will remain and not be reviewed or
 addressed, undercutting the improvement PHP is trying to make.

 Reminder:
 > * 1 x `utf8_encode()` in `tests/phpunit/tests/kses/php`

 This instance of `utf8_encode()` was already removed in [57861].
