Rt3 installation error AddDefaultCharset

Hello Everyone,

I have installed rt3 on redhat 8. Now after installation when I start the
apache server I get the following error due to AddDefaultCharset

If I comment this line the server starts up fine. How do I enable this
default setting? Do I need to load any specific module in the server

DocumentRoot "/usr/local/rt3/share/html"

ServerName machinename

AddDefaultCharset UTF-8

PerlModule Apache::DBI

PerlRequire /usr/local/rt3/bin/webmux.pl

<Location />

    SetHandler perl-script

    PerlHandler RT::Mason



Invalid command ‘AddDefaultCharset’, perhaps mis-spelled or defined by a
module not included in the server configuration
