Is it possible to use chinese named attachements ?

Hello,

We have chinese named attachments but we can't use it. If we try to drag and drop or select it inside the folder browser, the attachment widow close. If we put it inside a folder like sage's temp folder and try to select it with the SageX3 browser, we don't see any chinese file in the list.
This issue as been constated in V12 and 6.5.
Do anything is necessary to use chinese named attachements ? Is it possible with Sage X3 ?

Best regards,
