description: On 2.0 i've an database, where was several grants for users, which names was in win1251 letters.
2.0 restores this db without errors, but when i try to restore it's backup under 2.1 - got error:
gbak: restoring privilege for user SYS$GROUP_ADD
gbak: restoring privilege for user ?????
gbak: ERROR:arithmetic exception, numeric overflow, or string truncation
gbak: ERROR: Cannot transliterate character between character sets
gbak: ERROR: At trigger 'RDB$TRIGGER_9'
gbak:Exiting before completion due to errors

is it problem of 2.0, which can't store unicode_fss correct or bug of 2.1?
How can such databases can be restored on 2.1(except of deleting rows from user_priveleges)?
