export dataset to insert command

Hello,

when I create insert command via export dataset, all CR charaters disappear, only LF characters stay in data.
I have to make correction after insert:

UPDATE

SET =REPLACE(, CHR(10), CHR(13)||CHR(10));
commit;

Do you know if it is error or are there any setup of this “feature”?

Toad for Oracle Base 11.0.0.116

Thanks
Pavel
