Remove BOM(Byte Order Marker) from UTF-8 files.
Wrote this because I had some legacy source codes of several Android projects in UTF-8 with BOM, but couldn't find any software to do batching BOM removing operations on MAC OS or Windows.
##Usage
bs.py [-h] [--type TYPE] path
path: path of the target folder or file
-h, --help: show this help message and exit
--type TYPE: file type， if assign the file type, only this type's file will be converted.
###Examples
Convert all files under a folder:
python bs.py /path/to/the/target/folder
Convert all java files under a folder:
python bs.py /path/to/the/target/folder --type java
Convert single file:
python bs.py /path/to/the/target/filename
