Encoding problem when uploading RDF to triplestore Blazegraph

[damorenov]

We use Gleaner CLI and follow the procedure at https://book.oceaninfohub.org/indexing/cliDocker/index.html with Minio Client and minio2blaze script. Data for indexing are being encoded in UTF-8 and are generated dynamically, for example http://20.124.232.205:8081/api/json?projectId=2, and we have a sitemap with all the projects for indexing at http://20.124.232.205/pr/sitemap.xml (test version).

Gleaner is working fine and with minio client we checked Spanish accents:

But when uploading RDF to the triplestore the accents are converted to "??" characters in the blazegraph client and the endpoint:

We tried to set the UTF-8 encoding in the minio2blaze (curl -X POST -H 'Content-Type:text/x-nquads; charset=UTF-8'), create a temporary file to save the stdin of the minio client and secure the UTF encoding and then pass it to the triplestore and finally, changing the JAVA_OPTS in gleaner-IS.yml to include some flags by a comment on blazegraph's github (blazegraph/database#206 (comment)), but we are unable to display any accents.

Thanks in advance
