If your are using hyperref, you can use \"o (or "o with german packages):

  \usepackage{ngerman}
  \usepackage{hyperref}
  \hypersetup{%
    pdfauthor={Peter Schr"oder},
    pdftitle={...},
  }

And you can use Unicode with option \usepackage[unicode]{hyperref}

But I doubt that you can see the sqrt symbol, but AR cannot
display all Unicode symbols, see the hyperref test file testbmu.
For details, see my talk in hyperref/doc/.
