Usage: check_language_files_not_BOM.py [root]
|
|
This script will check the presence of language files encoded in UTF-8 with
|
|
BOM. It will return 0 if none is found. Otherwise, it will print the path of
|
|
the violating files and return an error code.
|
|
If root is not specified, it will use the current directory.
