Can you give an example and problem (logs) you encountered?

Here is an example I tried and which is working:

Document folder = (Document) session.newRequest("Document.Create").setInput(
                "/").set("type", "Folder").set("name", "TestFoldereé").set(
                "properties",
                "dc:title=TestFoldereé\ndc:description=Simple container").execute();
Document root = (Document) session.newRequest("Document.Fetch").set(
                "value", "/TestFoldereé").execute();
PaginableDocuments docs = (PaginableDocuments) session.newRequest(
                "Document.PageProvider").set("query",
                "SELECT * FROM Document WHERE ecm:path = ?").set(
                "queryParams", "/TestFoldereé").set("pageSize", "2").set("page",
                "0").execute();

I have always a non empty result. Thanks

Unfortunately, i don t yet have access to the portlet running the automation client. However these automation traces (one querying for an accented title and another one for an accented path) suggest that the problem might come from the portlet : the encoding is the same in both cases.
