Why flies encoding from htaccess?

Question

PHP

In the VirtualHost domain config on the server:
AddDefaultCharset off
I upload the site on static files. The file is ANSI encoded in meta 1251 (yes, I know that utf8 is better, but it happened historically). Everything works correctly.
I upload htaccess with the following content:

RemoveHandler .html .htm .php
AddType application/x-httpd-php .htm .html .php
DirectoryIndex index.php index.html index.htm
Options All -Indexes

The text on the site flies like this:

Why are there no encoding directives in htaccess?

Answer 1

AddDefaultCharset WINDOWS-1251

Answer 2

If php version >= 5.6, then default_charset might be the problem .
