Hi ,

The most likely cause is character encoding or a Unicode dash character in the REST API response.

First, check the raw API response in Postman. If the character is already incorrect there, the issue is with the API/source data or encoding.

If the API response is correct but OutSystems displays it incorrectly, check that the API response uses UTF-8 encoding (application/json; charset=utf-8).

Also verify whether it is actually a normal hyphen - or another Unicode character such as – (en dash) or — (em dash).

As a workaround, you can normalize the character in OutSystems using Replace(), but ideally the encoding/source data should be fixed.
