bash cgi script with chinese

I simply use the default lighttpd.conf but just enable the cgi module.

The script listed bellow just works fine in the urxvt, with proper Chinese characters output. However, when visited by a browser, these Chinese characters just gone, leaving no spaces?If substitute "/usr/bin/fortune-zh" with "/usr/games/fortune" which outputs just English words, every thing is ok. So, How to get it done with Chinese ouput in a browser?

$cat for

#!/bin/sh
echo "Content-type: text/html" 
echo "" 

echo "<html><head>";
echo '<meta http-equiv=Content-Type content="text/html; charset=utf-8">';
echo "<title>Fortune</title>";
echo "</head><body>";
for myline in $(/usr/bin/fortune-zh | sed -e '1,$ s/.[[0-9]*m//g' -e '1,$ s/ /__s__/g' -e '1,$ s/\t/__t__/g' )
do
    myline=$(echo $myline | sed -e '1,$ s/__s__/ /g' -e '1,$ s/__t__/\t/g')
    echo "<pre>$myline</pre>" 
done
echo "</body></html>";
