Im using Logica SMPP api. Im able to send plain english messages with default data coding as "0"
Now if i want to send sms in other language such as hindi or chinese, what are the different values i should set..

Should i create a UDH for the same ?
wht data coding should i use?
wht esm class should i set ?
should i send the data as unicode?

any suggestions on this will be very useful,
