Oups!
False Alarm.
Check utf-8 encoding for filenames: On (not auto).
A directory list from Putty:
<invalid hyperlink removed by admin>
A directory list from WinSCP:
<invalid hyperlink removed by admin>
Settings on Putty:
<invalid hyperlink removed by admin>
I connect to my OpenSSH Server of my Nokia N900 device.
Many files in this device and in my PC have Greek name.
When I send a greek named file from my PC to Nokia N900, WinSCP fail to keep the original name and throws an error message.
When I view the file list on my Nokia N900, greek filenames appear wrong (they are in utf-8 charset because they have double character length).
File list appears right in my PC.
