Question new httpd seems to ignore AddDefaultCharset Off

[tkalfaoglu]

This is not exactly PLESK, so sorry about that..

Migrating from one Obsidian (Centos 7) to another (Centos 8).. I noticed that a transferred web site, www.ixir.info to be exact, does not display correctly.
The site was made with Windows-1254 a long time ago, but the browser insists on using UTF-8.

I checked the httpd.conf and found the
#AddDefaultCharset UTF-8

commented.. I even added another, saying
AddDefaultCharset Off

Neither of them helps -- my browser still switches to UTF-8 visiting that site, but I checked and its source code clearly says Windows-1254..
Any ideas how to fix this?

Many thanks, -t
