Subject: [core] RFC7252 discover - RFC6690 / special characters

Dear list,

I stumbled over a detail in the coap-discover, and I'm not sure, if my
interpretation is the right one:

How are special characters in the resource path handled, e.g. "[".

My interpretation of RFC6690,
https://datatracker.ietf.org/doc/html/rfc6690#section-2.2 is to report
such a resource in the discover response as relative URI with:

"</intf/%5B0:0:0:0:0:0:0:1%25lo%5D:5684>"

(The "[" is encoded as "%5B".)

Is that the intended behavior?
I couldn't find an example in RFC6690, which covers that case.

best regards
Achim Kraus
