Create a properties file in QSH with the correct codepage 437 - How?

Ok folks...

My data corruption problems stem from the creation of the properties file in 
QSH:

echo "serverip=$server" > /opt/AVAps/bin/psunix.properties
chmod 600 /opt/AVAps/bin/psunix.properties
echo "mixedcaseuserids=true" >> /opt/AVAps/bin/psunix.properties
echo "description=$desc" >> /opt/AVAps/bin/psunix.properties
echo "http.port=$httpport" >> /opt/AVAps/bin/psunix.properties
echo "keystorepwd=$key" >> /opt/AVAps/bin/psunix.properties
echo "debug=false" >> /opt/AVAps/bin/psunix.properties

Standard out has a codepage of 37 (the default display code page).

I need a code page on the properties file of 437.  How do you create your 
properties files
in QSH?
