Wrong charset output when using var_dump()

Question

I'm using Opencart 2.1.0.2

When I'm debugging with var_dump() I have output with the wrong charset. But if I use die after that I have a nice output.

This's the bad one:

At the very top of index.php I put echo mb_internal_encoding(); die; and I got ISO-8859-1. So then I put mb_internal_encoding('UTF-8') before that. But it didn't help.

Also, I recursively checked all files on charset with mb_detect_encoding($file). All files have UTF-8 or ASCII charset.

php.ini has default_charset = UTF-8

I'm using hosting Ukraine. I set UTF-8 as a default charset.

But none of these things helped.

Do you guys have any ideas?

Answer 1

I found the problem. This line in index.php causes the bad output. I have no idea why. So I just commented it out.

$response->setCompression($config->get('config_compression'));
