Oracle 11g Installation How to select Database Character Set

Question

Hi,
I am Installing oracle 11g R2. After installation I had verified the character set it was AL16UTF16 but I wants to set AL32UTF8 charater set at the time of oracle installation only. I can't see the character set setting opetion at the time of installation because I am selecting the installation option " Install database softerware only" and after installation of oracle software manually I am creating the database. Please help me how can I set the character set at the time of oracle installation or at the time of database creation.
My question is-
How can I set the AL32UTF8 character set in above scenario?
Why It is showing AL16UTF16 character set even I did not define any thing?

Answer 1

But is there any choice to set the NLS_CHARACTERSET at the time of manually database creation. Actually For creating the database i am using one shell script for seting the parameter values in init.ora file so can I set the parameter at that level(at the time of creating init.ora using manually database creation). like
## Original init.ora file created by manual database creation tool on ${DATE}.

Is it correct?
