Support special characters for Assignments

[tarebyte]

Closes #266

[tarebyte]

@johndbritton the more I think about this, the more I believe we should not support special characters.

We should instead handle them how GitHub does, for example an Ü becomes a -. This means that we should also add some client side warnings so that the user knows what they're assignment name will be.

What do you think?

[johndbritton]

We shouldn't change user input, so if the title includes special characters, we should display them (as GitHub does). I'm fine with replacing special characters in URL slugs, though.

[tarebyte]

I agree about still displaying special characters, the thing is though GitHub repos don't support special characters. It just replaces everything with one dash.

This is an example of that scenario right now.

Maybe we should warn the user when they make the title, something similar to this.

Names of assignments aren't GitHub Repo names. This is a perfect example, the assignment name should be able to use special characters even if the repository cannot.

If anything, I think this is another reason why we shouldn't put the assignment name in the URL and potentially another reason to get rid of title all together.

[johndbritton]

Names of assignments aren't GitHub Repo names.

Except for the fact that we create the repo names based on the name of the assignment. Is there another way we could make these names?

[johndbritton]

Perhaps we create a slug field that is used to generate the repo name on GitHub and allow teachers to set that. If we wanted to get fancy, you could display two fields title and slug and have the slug field auto-populated but editable by the user.

We already have the slug column on those models so we could add those to the form.

That is very doable, I'm 👍 for it.
