When you create a bat or cmd file in Microsoft Visual Studio 2008 it will be saved as UTF-8 encoding, but bat files should have ASCII enconding.
Running a bat file starting with @echo off, creates an error:

‘∩╗┐@echo’ is not recognized as an internal or external command, operable program or batch file.

Saving the file as ASCII in Microsoft Visual Studio 2008 solved the problem
