MySQL X DevAPI connectors utf8 issue

[Jens hansen]

The function 'mysqlx_collection_modify_set' should be capable of updating or creating the key name "_b_ke-y$fkæøåÆåø", but it is not performing any action when attempting to do so. However, it works as expected when the key name is something like "test".

I'm using it in this way:

mysqlx_collection_t *collection_ = mysqlx_get_collection(schema, collection, 0);

mysqlx_stmt_t *stmt2 = mysqlx_collection_modify_new(collection_);

mysqlx_set_modify_set(stmt2, "_b_ke-y$fkæøåÆåø", PARAM_EXPR("{\"username\":\"test\"}"), PARAM_END);
