REST interface does not accept accented characters

[xatapult]

What is the problem

I have XML files in my database with accented characters in their filenames that I would like to access with REST. For instance /db/TEST/bäk.xml

I do not seem to be able to access this file using the REST interface. I tried (in the Chrome's address bar) http://.../exist/rest/db/TEST/bäk.xml and http://.../exist/rest/db/TEST/b%C3%A4k.xml but all yield the same result: Document /db/TEST/bäk.xml not found

I suppose the problem is with multibyte Unicode characters in general?

BTW, I also need this for the PUT and DELETE REST functionality but that fails as well.

What did you expect

The contents of the file

Describe how to reproduce or add a test

Create a file with an accented character somewhere. Try to retrieve it using REST

I suspect that underlying this is the phenomenon I described in #1824 (comment). I don't think I had ever quite encountered this aspect of it - where there's no way at all to address a resource over REST - though I am able to see it over WebDAV via http://localhost:8080/exist/webdav/db/b%C3%A4k.xml. That URL opens up just fine for me in Chrome. But if I change webdav to rest, I get your result:

HTTP ERROR 404

Problem accessing /exist/rest/db/b%C3%A4k.xml. Reason:

Document /db/bäk.xml not found
