Hi Pradeep.
At the end of the day, a character is stored as a byte sequence on disk, and a code page defines the mapping between the byte sequence and any given character.The code page determines what character you can see and enter, therefore different code pages map different characters to the same byte sequence.
I suggest you to first check if your system is a Unicode system by checking the System menu->Status option->Unicode system field. I'll assume it is.
Then, please run report RSCP0018 (optionally also RSCPINST and then select Current NLS config pushbutton).
These reports will show you the actual configuration of languages and code pages of your Application Server. Please check that the correct languages and code pages are configured. If you need to know more about code pages configuration, please check Note 42305, which explains pretty well the whole process.
Kind regards, and good luck.
Federico
