This is the error, now your database is screwed.
Try to put back the preceding and use a valid method to change the character set but I advice you to restore from a valid backup.

EXP-00091 Exporting questionable statistics

Cause: Export was able to export statistics, but the statistics may not be useable. The statistics are questionable because one or more of the following happened during export:

- A row error occurred, client character set or NCHARSET does not match with the server, a query clause was specified on export,


- Only certain partitions or subpartitions were exported, or a fatal error occurred while processing a table.

Action: To export non-questionable statistics, change the client character set or NCHARSET to match the server, export with no query clause, or export complete tables. If desired, import parameters can be supplied so that only non-questionable statistics will be imported, and all questionable statistics will be recalculated.

You have to manually tell exp utility to ignore the statistics by using
statistics=none 

along with other export options
or
set the proper values for NLS_LANG in your OS environment.
export NLS_LANG=yourValue.

Hi,

Same issue regarding character set. I have changed the character
set to original one i.e. AL32UTF8 as usually by updating props$ view.

Now I tried to change the character set from AL32UTF8 to
US7ASCII with the below procedure.

1. Ran the csscan utility.
2. Restarted the database with restrict option.
3. ran the csalter utility.

But I got the message like below.

This script will update the content of the Oracle Data Dictionary.
Please ensure you have a full backup before initiating this procedure.
Would you like to proceed (Y/N)?y
old 6: if (UPPER('&conf') <> 'Y') then
new 6: if (UPPER('y') <> 'Y') then
Checking data validity...
Exceptional data found in scanner result

PL/SQL procedure successfully completed.

Checking or Converting phrase did not finish successfully
No database (national) character set will be altered
CSALTER finished unsuccessfully.



Observed that in csscan, got the below issue.

ORA-30967: operation directly on the Path Table is disallowed

CSS-00144: failed to scan table XDB.XDBACL_PATH_TAB


Can any one please help me....

Most probably this table is been protected.
Are you really using XDB options?
Check metalink. There are few related issues reported.
