ZCM11 with Cumulative Agent Patch 1.

I have a bundle which uses "Edit text file" install action to create a .bat file and then launches that .bat file.

Problem is that some garbage is being put at the beginning of file. First line of "Content of the file" field in ZCC is:
@echo off

First line of the .bat file as it is created on workstations is:
╗┐@echo off

This of course causes an error in the launch action.

I have tried deleting the first line of the file content, thinking that maybe there are some 'invisible characters' in the beginning, but then the garbage was put at the beginning of the next line.

Anyone else seeing this?
