Hello, thanks, awesome job, Thanks a lot for contributing, and sorry if I took some time to review your changes.
Nice to add a new site for the tool, I want to ask you (if you have the patience) to fix some stuff, nothing big, just some things that make future maintenance easy, do you think we can iterate a bit to improve those small issues ?

[iemejia]

One extra question have you tried your code on windows? We use to have tons of problems with chinese characters in windows, that's the reason why we ultra simplified everything to be ASCII. Anyway I think this solution is not future proof and maybe we must fix it as part of your PR (or I will do it in a future one).

@iemejia Hello! I'm very pleased to improve my code or, if possible, help with the further maintenance of the project. I'll try coping with the windows encoding issue maybe later this week.

[iemejia]

Awesome, this is great news, don't hesitate to ping me if you need anything. More hands that can help us improve the project are always welcome.

I've tested with Windows and now it seems to work well (with Python 3).

@mcfloundinho, can you please check which changes are needed now that edX has changed their structure? Do your proposed changes still work? Please, take a look at my changes in b6c77a6 in particular.

@mcfloundinho
Hi, thanks for your code. With your xuetangx change, and @anmolsahoo25 's 403 fix, Xuetangx.com downloads fine, and works on windows.

[rbrito]

Can you rebase your changes to the current master branch?

[yiwenlu66]

@rbrito Yes, I've done the rebase. Sorry for the delay.
