Ok, this works:

lib/IniConfig.php:

function _unknown_charset_warning($error) {
     if (preg_match('/^charset \`.+\' not supported, assuming iso-8859-1/',
                    $error->errstr))
         return true;  // Ignore error
     return false;
}

and inside fixup_static_configs() after $charset = CHARSET;

     if (defined('IGNORE_CHARSET_NOT_SUPPORTED_WARNING') and 
IGNORE_CHARSET_NOT_SUPPORTED_WARNING) {
         global $ErrorManager;
         $ErrorManager->pushErrorHandler(new 
WikiFunctionCb('_unknown_charset_warning'));
     }

Now put in config.ini for all charsets not listed below the lines:
; Most exotic charsets are not supported by htmlspecialchars, which 
prints a warning:
; "charset `bla' not supported, assuming iso-8859-1"
; Even on simple 8bit charsets, where just <>& need to be replaced.
; See <php-src>/ext/standard/html.c
; We can ignore these warnings then.
IGNORE_CHARSET_NOT_SUPPORTED_WARNING = true
