latex , matematika s cestinou

[Vrablik Zdenek]

Dobry den, chtel bych pozadat o radu, co mam udelat, aby se mi zobrazovali
fonty v matematice cesky

 \( y^k_s=\left\{
                        \begin{array}{l}
                            1,  pokud ěščřřžú\\
                            0, pro ostatní
                        \end{array}
                \right.
        \)

toto mi nezobrazuje mezery v textu a ani pismena s diakritikou

This is TeX, Version 3.14159 (Web2C 7.3.1)

pouzivam cslatex v distribuci Mandrake 9.0
hlavicka dokumentu vypada takto
\documentclass[11pt,oneside,a4paper]{report}
\usepackage{czech}
\usepackage{graphics}
\usepackage[dvips]{epsfig}
\usepackage{ifthen}

\setlength{\textwidth}{16cm}
\setlength{\topmargin}{-0.5cm}
\setlength{\textheight}{23.7cm}
\setlength{\oddsidemargin}{0.5cm}
\setlength{\evensidemargin}{-0.8cm}
\setlength{\footskip}{1.2cm}
\setlength{\parindent}{0.5cm}
\setlength{\parskip}{5pt}


dekuji za radu.

s pozdravem
