in continuation to previous line, there are two types of characters are used.
if we put these two characters in 'ascii', will give its chr value. Like-

select ascii ('') a, ascii('
') from dual


as result first char's ascii vale is 4 and another is 10. Char value 10 means
it is line change character. while Ascii value 4 will be some character in
Swedish(guess as google says).

Then your transfer from front to back end is wrong.
