How to query REST Service with a parameter containing special characters like +,. etc in OIC

We are trying to use REST Service and pass a parameter containing + or , in the parameter value in OIC.

How can we achieve this in OIC?

I know from postman, we have to use like this:

/hcmRestApi/resources/11.13.18.05/jobs?q=Name = 'B5H-C++'

is converted to

/hcmRestApi/resources/11.13.18.05/jobs?q=Name = 'B5H-C%2B%2B'

Any help will be much appreciated.
