Issue in import file Excel

[_AnonymousUser]

Hi all,
I'm trying to import a lot of excel files using Talend etl jobs, but, when i create the metadata the following message is displayed:

Warning:  Usage of a local non-builtin name
Preview error. Some settings must be changed.
Note: Preview errors are generally due to a wrong encoding setting.
org.talend.designer.runprocess.shadow.ShadowFilePreview.preview(ShadowFilePreview.java:90)
org.talend.metadata.managment.ui.utils.ShadowProcessHelper.getCsvArray(ShadowProcessHelper.java:383)
org.talend.repository.ui.wizards.metadata.connection.files.excel.ExcelFileStep2Form$PreviewProcessor.nonUIProcessInThread(ExcelFileStep2Form.java:1042)
org.talend.commons.ui.swt.thread.SWTUIThreadProcessor$1.run(SWTUIThreadProcessor.java:74)

Files I'm trying to import have 97-2003 excel format (xls) and I'm using UTF-8 encoding.
If I convert these files using excel the error doesn't occur more.
Because I need import these files automatically no convert operation shoud be performed.
I use TOS DI 6.0.0
Does anybody can help me, please?

Hi all,
I can confirm that the described bug was solved in TOS DI 6.1.
Congratulations to the development team for its work!
