Summary0002313: var_dump does not output some Russian characters
Description

When outputting a string, var_dump does not display some of the Russian characters encoded in Windows-1251.
Or rather, characters whose codes are greater than or equal to F0

Steps To Reproduce

Install Windows 10
Download the latest version of PHP (8.4) c https://windows.php.net/download/
Install Apache 2.4 and PHP 8.4
Create a script test.php encoded in Windows-1251
header('Content-Type:text/html;charset=Windows-1251');
$s = '...'; // here is a complete set of Russian characters
echo 'php: ', phpversion(), ',  xdebug: ', phpversion('xdebug'), '

';
echo $s;
var_dump($s);
Execute in the browser http://localhost/test.php

Additional Information

If you disable the xdebug extension, the string is displayed without problems.

There is way too little information in this report.

There is no actual script to test, and I'm certainly not going to "Install Windows 10".

It is also not "urgent" or a "crash".

Even if you provide an actual full test case, I sincerely doubt there is a bug in Xdebug here; and merely something where you are messing up character sets.

Unfortunately, there is no way to send a script here. There is no way to request a test in another version of Windows.
It's not clear what to do with a broken xdebug.
Most likely, this won't work in another OS either.

It might be clearer this way.
Everything worked fine in php 7

To reproduce this bug, you need to run a simple 4-line script. The question is, how do I pass this script to you?
