Describe the bug
In some cases, irIIIFService will try to request a Fedora resource by encoding parts of a URI from Fedora that has already been encoded. This causes irIIIFService to fail to request the RDF resource with a 404 and results in the Manifest not generating.

To Reproduce
Steps to reproduce the behavior:

  1. To see this in action, checkout the third Manifest in this Collection: https://api-pre.library.tamu.edu/iiif-service/fedora/collection/bb/97/f2/3e/bb97f23e-803a-4bd6-8406-06802623554c/basbanes-exhibit-texts-20240924
  2. Click on the Manifest https://api-pre.library.tamu.edu/iiif-service/fedora/presentation/bb/97/f2/3e/bb97f23e-803a-4bd6-8406-06802623554c/basbanes-exhibit-texts-20240924_objects/17
  3. We get an innocent enough error message: RDF not found! https://api-pre.library.tamu.edu/fcrepo/rest/bb/97/f2/3e/bb97f23e-803a-4bd6-8406-06802623554c/basbanes-exhibit-texts-20240924_objects/17/pages/page_0/files/blumberg-holiday%20card_1.jpg/fcr:metadata, but that URL resolves to a 200. Hmmmmm. 🤔
  4. If we dig deeper and look at the logs, we can see what's actually happening: o.s.web.client.RestTemplate : HTTP GET [https://api-pre.library.tamu.edu/fcrepo/rest/bb/97/f2/3e/bb97f23e-803a-4bd6-8406-06802623554c/basbanes-exhibit-texts-20240924_objects/17/pages/page_0/files/blumberg-holiday%2520card_1.jpg/fcr:metadata](https://api-pre.library.tamu.edu/fcrepo/rest/bb/97/f2/3e/bb97f23e-803a-4bd6-8406-06802623554c/basbanes-exhibit-texts-20240924_objects/17/pages/page_0/files/blumberg-holiday%2520card_1.jpg/fcr:metadata) 2024-09-27 14:07:46.864 DEBUG 1 --- [nio-8080-exec-4] o.s.web.client.RestTemplate : Accept=[text/plain, application/json, application/*+json, */*] 2024-09-27 14:07:46.898 DEBUG 1 --- [nio-8080-exec-4] o.s.web.client.RestTemplate : Response 404 NOT_FOUND 2024-09-27 14:07:46.899 ERROR 1 --- [nio-8080-exec-4]
  5. Notice that the Fedora Resource being requested is blumberg-holiday%2520card_1.jpg. In Fedora, it is blumberg-holiday%20card_1.jpg, and on disk it was blumberg-holiday card_1.jpg. In other words, we have a file with spaces, Fedora (or MAGPIE) encodes the space as %20, and then irIIIFService thinks the % needs be encoded as %25, and we end up with %2520.

Expected behavior
irIIIFService attempts to determine if a resource uri is already encoded instead of reencoding.

Additional context

A couple of things worth thinking about:

  1. Is MAGPIE (how this was originally ingested) doing the initial encoding or Fedora? If it's the former, could we have unencoded resources in Fedora that would be affected by this change (dropping encoding all together)?
  2. Wouldn't all this be avoided if we had an expectation that filenames followed a certain pattern prior to ingest and that spaces and other certain characters weren't allowed? I think I can advocate this for the future.

Just a note that it looks like the RDF spec requires that URIs are encoded so this is almost certainly something Fedora is doing when a new resource is minted. For that reason, I don't see why irIIIFService would even need to encode these bits to begin with.
