I have the same problem with the local fr_BE , under Mint and Pop!Os (ubuntu 20.04) for php8.0 and
php8.1.
On the other hand with php7.4 no problem.
I can't put accented characters in the response of a readline() function either.

This works on 7.4 and 8.0:

var_dump(setlocale(LC_ALL, 'en_US.UTF-8'));
readline('doména ěščřžýáíé');

This crashes on 7.4 and 8.0:

var_dump(setlocale(LC_ALL, 'C'));
readline('doména ěščřžýáíé');

Locale-dependent crashes in libedit, this is horrible.

When using the Czech diacritics in readline parametter, whole application crashes.

It works in PHP 7.4.

---------------
<?php
readline('doména ěščřžýáíé');

Actual result:
--------------
Neoprávněný přístup do paměti (SIGSEGV) (core dumped [obraz paměti uložen])

Translated to EN: Unauthorized Memory Access (SIGSEGV) (core dumped)
