can not handle the output from python build-in lib(while using argparse)

See original GitHub issue

I have below code :

from __future__ import unicode_literals, absolute_import

......

def main():
    global ROOT_PATH
    parser = argparse.ArgumentParser()
    parser.add_argument('-p','--path', default='__here__')
    print 1
    args = parser.parse_args()
    print 2
    p = unicode(args.path, 'gbk')
    if p == '__here__':
        ROOT_PATH = os.getcwd()
    else:
        ROOT_PATH = p

    for sf in get_sub_folders(ROOT_PATH):
        process_folder(sf)

My windows7 cmd encoding is gbk(a Chinese encoding)

Chinese work fine

Generally, there may problem with giving Unicode argument to a Python 2 script, the bytes in sys.argv may even not be a faithful representation of the original string. See #20 . Maybe I’ll add code like that to win_unicode_console.

There is some progress with #20. But for your particular code, you may turn sys.argv to Unicode before parsing rather than after:

args = [unicode(arg, "gbk") if not isinstance(arg, unicode) else arg for arg in sys.argv]
args = parser.parse_args(args)
