Android Project Compiled with Ant doesn't compile, Illegal Character Error

I am using ANT to compile an Android app that I have built. It sounds weird and probably doesn't make a difference, but I used the Android SDK to build a new project and then I used .NET to programatically modify a couple files within the project so it would build the way I wanted.

I have loaded the project into Eclipse, and it appears to compile properly, but when I run it through ANT, it doesn't compile properly. The error seems to say that I have a '?' in the one activity in the project. I have confirmed multiple times, there is definitely no '?' in the file.

Error:

 [javac] C:\IBE_temp\_RTS\ANTTest\$SimpleTest\proj\src\com\infosol\SimpleTest\MyActivity.java:1: illegal character: \65279
        [javac] ?package com.infosol.SimpleTest;
        [javac] ^
        [javac] 1 error

If any one has thoughts on what I am doing wrong, I would really appreciate it. Not sure what will be helpful, but below are the results from the ANT output.

The command line:

C:\IBE_temp\java\bin\java -Dant.home="C:\IBE_temp\Packager\ANTSDK" -classpath "C:\IBE_temp\Packager\ANTSDK\lib\ant-launcher.jar" org.apache.tools.ant.launch.Launcher release -v
