Hi Sonal
No it is not unusual. If it is a normal pipe character - | (ASCII code 124), then you can achieve this using File Content Conversion on your receiver File/FTP channel. Search for File Content Conversion or FCC on SCN, and you will have lots of resources, blogs, wikis on how to achieve that.
You need to specify the fieldSeparator in FCC as | or using hexadecimal value '0x7C'.
