Thanks for the pull request, and welcome! The Rust team is excited to review your changes, and you should hear from @shepmaster (or someone else) soon.

If any changes to this PR are deemed necessary, please add them as extra commits. This ensures that the reviewer can see what has changed since they last reviewed the code. Due to the way GitHub handles out-of-date commits, this should also make it reasonably obvious what issues have or haven't been addressed. Large or tricky changes may require several passes of review and changes.

Please see the contribution instructions for more information.

Since you've moved the Unicode-related things to a new PR, you should remove them from this PR, leaving only the mut change. Go ahead and do that, squashing your commits, and we can merge this.

I'm not sure it's still possible, because I deleted this specific fork by mistake. Should I make a new PR in this case, or is there another way?

Huh, I'm surprised it's possible to delete a fork with open PRs. It appears that opening a new PR is the best alternative.

[tomasz-rozanski]

I'll create a new PR, then.
