hi panos78, you're the greek translator, right?
Well, the problem is that Greek uses some characters that are not the same as the english ones, and you have to encode using the HTML syntax:
&code; or
&#number. It isn't a problem with the format in which the file is saved, which should be ANSI.
Mnjul had the same or a similar problem when translating the web into chinesse. Read the thread
Request: A translation program for website translation. There someone suggest a program that seems to work well.
