Hi. There are three possible conversions when exporting and importing:
1) from the source database character set to the user session character set(based on setting for NLS_LANG during export) 2) from the export file character set to the user session character set base d on the setting for NLS_LANG during import) 3) from the user session character set (criteria noted in #2) to the target database character set.I would suspect that the user session character set during import is not the same as the character set of the export file. The conversion noted in #2 above is only valid for single-byte character sets. For multibyte character sets, the import file's character set must be identical to the export file's character set.
