Quote: the export Modified the rows and the rows were corrupted.
Not if you are in the character set your database which is ('or should be) most often the case.
Let's see what is said:
Export done in WE8MSWIN1252 character set and AL16UTF16 NCHAR character set
So you exported with an NLS_CHARACTERSET of WE8MSWIN1252 which is fine if your database is also in this character.
server uses AL32UTF8 character set (possible charset conversion)
And so, why do you care about code points? The only problem is if you (wrongly) let NLS_LENGTH_SEMANTICS to BYTE or create your VARCHAR2 field specifying the length is in BYTE.
Regards
Michel
