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.

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.
