You may need to retrieve a table schema that contains columns written with special characters like Chinese, Japanese, Korean. In this case, you need to enable Talend Studio to read the special characters. To do so:
From the menu bar, click Window > Preferences to open the [Preferences] dialog box.
On the tree view of the opened dialog box, expand the Talend node.
Click the Specific settings node to display the corresponding view on the right of the dialog box.
Select the Allow specific characters (UTF8,...) for columns of schemas check box.
