CSV attachment in Mail with CRLF

Hello Experts

We have recently migrated from PI7.0 to PO7.4 which is on Windows.

But got an issue with interface which is file to mail in which we are sending CSV file as an attachement by reading the file.

But while generating the attachment through PI- UDF we have added "/r/n" to produce CRLF at the end of line in CSV attachement, but the attachment is having only Line Feed : "LF" not "CRLF"

Can some one please suggest any approach to achieve this.

We have tried many ways on changing encoding , text but the requred CRLF is not coming.

Thanks
