How to allow special characters using SharePoint REST API?

SharePoint Search REST query filter with special characters.

Special characters can indeed pose challenges when working with APIs like SharePoint REST API or libraries like PnP JS. These characters, if not handled properly, can cause issues such as code breaking or unexpected behavior.

By utilizing the encodeURIComponent method to encode the text, it effectively manages special characters.
