Registered Trademark symbol encoding

I am trying to run a collection with a registered trademark symbol in the incoming data file, but Postman is not encoding the character. If I encode it first (whether ®, ®, or %C2%AE), then Postman re-encodes it and breaks the request. I can’t seem to find any way to handle these characters.

Any ideas?

Hey @dugjonz81,

Welcome to the Postman community! :rocket:

Would you be able to provide an example of the file and how you’re using this in the request please?

Which version of Postman are you using to perform this action?

Hi @dugjonz81,

This issue usually happens because the registered trademark symbol (®) is a non-ASCII character, and Postman automatically encodes request parameters using UTF-8. If you manually pre-encode it (like %C2%AE), Postman will double-encode it — causing the request to break.

Solution:

  • Don’t manually encode the ® symbol. Just include it as is in your request body or URL — Postman will handle UTF-8 encoding correctly.

  • If you’re sending it in query params, wrap the entire URL in quotes or use the Params tab instead of typing the full URL.

  • Alternatively, replace ® with its Unicode escape (\u00AE) if you’re sending JSON data.

Example:

{

“brand”: “Coca-Cola\u00AE”

}

This ensures the symbol is transmitted properly without double encoding.
