By default, MzScheme writes strings in UTF-8. If you want Latin-1
output, then you could write something like

 (require (lib "port.ss"))

 (call-with-output-file "/tmp/xxx.txt" 
    (lambda (orig-p) 
      (let ([p (reencode-output-port orig-p "latin1")])
        (write-xml (h4:p "Olá") p)
        (flush-output p))))
