Want to export with Export: Release 9.2.0.1.0 from Oracle 11g database

Question

hi gurus,
I need to put a user's data from Oracle 11g to Oracle 9i. I heard, I had to do it using exp 9.2, so I installed Oracle 9i client (Export: Release 9.2.0.1.0 ) and tried to export data from Oracle 11g database but I got following character set error while exporting.
"Export done in WE8MSWIN1252 character set and AL16UTF16 NCHAR character set"
and exp crashes out.
(env. windows xp)
My questions:
1. may i need to set the character set of oracle 11g database to US7ASCII ?
2. is it reversable process to change character set from WE8MSWIN1252 to US7ASCII ?
3. or there is something else i need to do to get this problem fixed?
regards
