I tried but i dont knwo what the source encoding is and i left it as 437 but set the output as utf8 but still nothing.What the source encoding of my file is as it is now? I need to spcify it

I must admit I haven't followed the whole thread in it entirety, but how comes you don't know the encoding of your own file? Which was its initial one? How did it get mangled? Didn't you keep at least a backup copy of the original one?

Also the linux code you posted how doe it help? You mean that piconv supports utf8?

Exactly, except that it's not "linux code", whatever that may mean - it's at the bash prompt, but it wouldn't be much different at cmd.exe one (if you have a grep installed, that is) the point still being that not only does it mean exactly what you said, but also that it is available on any platform you may have a perl 5.8 installed.

The input encoding is UTF-8. The output encoding is windows-1253 and ISO-8859-7. The result is UTF-8. I thought that would be clear from Re^5: Encoding changed from Greek to somethign else.
