Symbols in password causes authentication errors

Authentication occurs with some symbols such as !@#$%*

python dl_all.py -u username -p Easypassword1@#$%* -v -a -q --headless
https://class.coursera.org/androidpart1-014/ androidpart1-014

Authentication fails with ^ in the password.

python dl_all.py -u username -p Easypassword1^ -v -a -q --headless

Could not authenticate: Cannot login on coursera.org.

Authentication with & in the password seems to ignore --headless option and tries to start Firefox which automatically updated itself to v47.

python dl_all.py -u username -p Easypassword1& -v -a -q --headless

'-v' is not recognized as an internal or external command,
operable program or batch file.

I think the best way to solve this problem is to change your password temporarily. U know today is June 27th... We don't have much time to waste on such easy-to-handle problem. Yet it is a bug as we know.

The way to get around this is by using quotes in your command line arguments. For example, if you do

python dl_all.py -u username -p "Easypassword1@%$&"

it should work.
