mp2: who is responsible for setting charset?

[JH Foo]

Hi all,   I have a need to set the charset in the header from the default 8859-1 to UTF-8. In CGI I simply set the header method($q->header(-charset=>'utf8');   Can anyone tell me the modperl equivalent, possibly with the Apache2::RequestRec or Apache::Request object? Thanks in advance. I really need to get this out of my hair asap.
