[2.7] bpo-24307: Fix unicode error in optparse with unicode value for %default by tirkarthi · Pull Request #9911 · python/cpython (original) (raw)

I found one more error where if the conflicting option is a unicode string then it throws UnicodeDecodeError.

from optparse import OptionParser

parser = OptionParser()
parser.add_option("-f", u"--file", dest="filename",
                  help="write to FILE. Default value %default",
                  metavar="FILE",
                  default=u"   ")

parser.add_option("-f", u"--   ", dest="filename",
                  help="write to FILE. Default value %default",
                  metavar="FILE",
                  default=u"   ")


(options, args) = parser.parse_args()
