### Feature Request / Improvement The [current Iceberg REST spec](https://github.com/apache/iceberg/blob/4c9f47d208b16921f825a66e24d0693f2b76b03b/open-api/rest-catalog-open-api.yaml#L1440) uses `0x1F` to separate the parts of a multipart (nested) namespace parameter in URL paths and elsewhere. However this [conflicts with the Servlet spec](https://jakarta.ee/specifications/servlet/6.0/jakarta-servlet-spec-6.0.html#uri-path-canonicalization) which calls for rejecting control characters (encoded or not), including the unit separator (`0x1F`), as "suspicious" and to return 400. Servlet containers enforce this (e.g. see https://github.com/jetty/jetty.project/issues/11495), making implementing the Iceberg REST spec difficult. Should a different, or at least alternative, separator character be selected to avoid conflicting with the Servlet spec? ### Query engine None -- This is an automated message from the Apache Git Service.
