How to use ASCII characters in a JSON call?

Hello,

I am having trouble using ASCII characters in a JSON call. This is the format of a sample string:



You can see it uses [RS](Record Separator, [GS] (Group Separator), and [EOT] (End of Transmission).

When I copy/paste this string into SoapUI, the program doesn't understand these characters:



According to http://www.theasciicode.com.ar/ : [RS] = Alt + 30, [GS] = Alt + 29, [EOT] = Alt+ 04

However, they do not appear the same way in SoapUI, which causes the test to fail:





Is there a way to make SoapUI read these ASCII characters so the test can be run?

Regards,

Jesse
