<?php
  $řetězec = "\"Babylónská rybka,\" odříkával tiše Stopařův průvodce po Galaxii";

You should use mb_strpos for this http://php.net/manual/en/function.mb-strpos.php

Because your string contains multibyte characters

You are working with strpos which counts bytes. Use mb_strpos

Thanks for good solution. The book from which I'm learning shows bugs or uncertainties, but when it comes to the PHP.net tutorials, PHP will learn the best.
