This code lets you convert multiple files in a directory to the desired encoding. The reason for this utility is the source control which is being used by my client doesn't support anything other than ASCII (7 bit). By default, some of the program creates files with UTF-8 encoding, which created the problem. I wrote this small program which will convert the files in a stretch and hence might save lot of time. Enjoy!
