Hi Team,
We have stored multibyte character data in our database columns.
We have a requirement to write these values to a fixed length file (position based). Since it is multibyte value, positions are getting extended and we cannot separate values at the right location.
Thanks,
Elaiyavel

How is this an Oracle question.
If you think "position" as "byte position" (and not "char position"), you can use a fixed-length character set then each character is in a fixed number of bytes.

What's the issue with using the classical way of generating CSV file.

Yes Absolutely, for multi byte characters, some characters occupies addition space and columns are written to file beyond the allocated position.
Is there a way to convert multi byte characters to single byte and write to a file.
This will help in the case when writing to fixed length files.

You're wrong, you can generate a file with Unicode with fixed-width charecter set.

Most likely you can generate a file with a proper 8-bit character set.
But as we don't know anything about your actual case we can't help more.
As Littlefoot asked you: post an example and specify with more details what you have and what you want.

You did not read the documentation link I provided above. It should remove all your confusions about character set.
