Get Header Text with special characters

Dear Experts,

I have written a program using READ_TEXT FM to get header text from Delivery.

However, one of the fields has a value "K&N".

When I get the header text, it shows "K<(>%<)>N".

How can I get back the normal text? Or do I need to replace the strings manually?

It is stupid.

Thanks.

Regards,

Cato
