Unicode Text on Linux and WindowsXP

[Panos Laganakos]

Hello, I am faced with an issue that came up recently.

I decided to make a small partition for my music on a local HDD  and I 
set it up to use ext3 FS.

Problem is that Greek text that was written on Windows appears as 
gibberish (regarding directories/files) on Ubuntu/Linux, and vice versa.

Any idea why this is happening? And which OS's fault is it? It could be 
mine I suppose :) Maybe I need to install something to better support 
greek chars coming from a windows accessible directory?

Thanks.
