Can ASCII control characters be entered to the raw body section. Is this possible?

Trying POST body that requires ASCII Control Character throughout the string/body. Characters/Value like 8 bit hex such as STX(start of text, Hex 02), ETX(end of text Hex 02), or any hex value in the Ascii hex range of 00-FF. Can POSTMAN do something like? Cannot be dependent on a specific header setting, I was hoping for something like URL encoding in the body to identify the character data

New to postman and novice but willing try if there are some ideas
