Batch Convert XCode String files, from utf-16 to utf-8

SITUATION

Old Version Xcode create utf-16 string file. It is not easy to diff changes.

TASK

Batch convert string files from utf-16 to utf-8.

ACTION

step 0: change one string file to utf-8

def convert(file_path: str, from_encoding: str, to_encoding: str):
    utf16_path = file_path
    utf8_tmp_path = utf16_path + ".tmp"
    try:
        with codecs.open(utf16_path,
                         encoding=from_encoding) as input_file:
            with codecs.open(
                    utf8_tmp_path, "w",
                    encoding=to_encoding) as output_file:
                shutil.copyfileobj(input_file, output_file)
shutil.move(utf8_tmp_path, utf16_path)
        return True
except Exception as e:
        # ori file maybe not from_encoding.
        os.remove(utf8_tmp_path)
        return False

step 1: batch convert

def batch_convert(dir_path: str):
    os.chdir(dir_path)
    for file in glob.glob("**/*.strings", recursive=True):
        file_full_path = os.path.join(dir_path, file)
        convert(file_path=file_full_path, from_encoding="utf-16", to_encoding="utf-8")

step 2: maybe need to change xcode editor’s config, if build failed.

Result

Easy to review diff in xcode string files.
