Code: 46/NOT_NFC in PATH: The IRI is not in Unicode Normal Form C

[zPlus]

Apache Jena RIOT version 5.2.0
Debian GNU/Linux 12 (bookworm)


I have a file called "Εισαγωγή_στον_στοχαστικό_λογισμό_2015_Χελιώτης.jsonld",
that I'm trying to load into a TDB2 database (content of the file below), but it
does not pass validation:


riot --validate
../data/nodes/Εισαγωγή_στον_στοχαστικό_λογισμό_2015_Χελιώτης.jsonld 
org.apache.jena.irix.IRIException:

However, just by renaming the file to something else such as "file.json"
everything works as aspected. There seems to be an issue with the file name, but
I cannot understand what's wrong about it. I'm wondering if this is a bug, or if
I'm missing something obvious.
